**Rational expressions**are

**multiplied anddivided**the same way numeric fractions are. To

**multiply**,first find the greatest common factors of the numerator anddenominator. Next, regroup the factors to make fractions equivalentto one. Then,

**multiply**any remaining factors.

Likewise, how do you multiply and divide rational numbers?

To **divide rational numbers**, you turn the**division** problem into a **multiplication** problem byflipping the second **rational number**. Then you go ahead and**multiply** the tops and bottoms together to get your answer.If you can simplify your problem before **multiplication**, youcan go ahead and do so to make your problem easier.

Beside above, what is division rational number? **Division of Rational Numbers**. To learn**division of rational numbers** let us recall how to divide afraction by another fraction. Divisor: The **number** whichdivides the dividend is called the divisor. Quotient: When dividendis divided by the divisor, the result of the **division** iscalled the quotient.

Then, how do you multiply exponents?

The **exponent** “product rule” tells us that, when**multiplying** two powers that have the same base, you can addthe **exponents**. In this example, you can see how it works.Adding the **exponents** is just a short cut! The “power rule”tells us that to raise a power to a power, just **multiply** the**exponents**.

What are the rules for dividing rational numbers?

**Divide Rational Numbers**. 1) If the **numbers**have the same signs then the quotient is positive. 2) If the**numbers** have different signs then the quotient is negative.When **dividing** two negative **numbers**, the quotient ispositive.

## How do you solve rational expressions step by step?

**The steps to solve a rational equation are:**

- Find the common denominator.
- Multiply everything by the common denominator.
- Simplify.
- Check the answer(s) to make sure there isn't an extraneoussolution.

## How do we divide decimals?

**divide**by is called the divisor. To

**divide decimal**numbers: Multiply the divisor by as many 10'sas necessary until we get a whole number. Remember to multiply thedividend by the same number of 10's.

## What are rational and irrational numbers?

**number**is

**rational**if we can write it asa fraction where the top

**number**of the fraction and bottom

**number**are both whole

**numbers**. Alternatively, an

**irrational number**is any

**number**that is not

**rational**. It is a

**number**that cannot be written as aratio of two integers (or cannot be expressed as afraction).

## What happens when you multiply two rational numbers?

**two rational numbers**is

**rational**.”

So, **multiplying two** rationals is the same as**multiplying two** such fractions, which will result in anotherfraction of this same form since integers are closed under**multiplication**. Thus, **multiplying two rationalnumbers** produces another **rationalnumber**.

## How is dividing rational numbers like dividing integers?

**divide**two

**integers**with the

**same**sign, the result is always positive. Just

**divide**the absolute values and make the answer positive. When you

**divide**two

**integers**with different signs, the resultis always negative.

## How do you solve integer exponents?

**integer exponents**are

**exponents**that are

**integers**.

**Positive integer exponents**indicate how many times we should multiply the base by itself.Negative

**integer exponents**tell us to first flip thenumerator and denominator and then multiply that number by itselfthe indicated number of times.

## How do you multiply expressions?

**multiply**the numerators witheach other and the denominators with each other. You can eitherstart by

**multiplying**the

**expressions**and thensimplify the

**expression**as we did above or you could startby simplifying the

**expressions**when it's still in fractionsand then

**multiply**the remaining terms e.g.

## Can you multiply exponents with different bases?

**you multiply**two numbers or variables withthe same

**base**,

**you**simply add the

**exponents**.When

**you multiply**expressions with the same

**exponent**but

**different bases**,

**you multiply**the

**bases**and use the same

**exponent**.

## How do you divide fractions with variables?

**divide algebraic fractions**, invert the second

**fraction**and multiply it by the first

**fraction**.Factorise the numerators and denominators. Then cancel the factorscommon to both the numerator and denominator before applyingmultiplication to obtain the answer.

## How do you divide radicals?

**Dividing Radicals**: When

**dividing radicals**(with the same index),

**divide**under the

**radical**, andthen

**divide**in front of the

**radical**(

**divide**any values multiplied times the

**radicals**). ANSWER:

**Divide**out front and

**divide**under the

**radicals**.

## How do you multiply fractions?

**To multiply fractions:**

- Simplify the fractions if not in lowest terms.
- Multiply the numerators of the fractions to get the newnumerator.
- Multiply the denominators of the fractions to get the newdenominator.

## How do you multiply a fraction times a whole number?

**multiply fractions**with

**whole numbers**,write each

**fraction**as an improper

**fraction**. To doso,

**multiply**the

**whole number**by the

**fractions**denominator, then add the numerator. Place this new

**number**over the old denominator.

## Do you multiply exponents in parentheses?

**parentheses**is raised to apower, the

**exponent**applies to everything inside the

**parentheses**. Simplify the expression, keeping the answer in

**exponential**notation. Only

**multiply exponents**whentaking the power of a power, not when

**you**are

**multiplying**terms. Then,

**you**add the

**exponents**.

## What is the rule of negative exponents?

**Negative Exponent Rule**: , this says that

**negative exponents**in the numerator get moved to thedenominator and become positive

**exponents**.

**Negativeexponents**in the denominator get moved to the numerator andbecome positive

**exponents**.

## What are exponents in math?

**exponent**refers to the number of times anumber is multiplied by itself. For example, 2 to the 3rd (writtenlike this: 2

^{3}) means: 2 x 2 x 2 = 8.

## What are exponent rules in math?

**Laws**of

**Exponents**.

**Exponents**arealso called Powers or Indices. The

**exponent**of a number sayshow many times to use the number in a multiplication. In thisexample: 8

^{2}= 8 × 8 = 64.

## Do you do exponents first or parentheses?

**You**might remember this as “Please excuse mydear Aunt Sally.”) This means that

**you should do**what ispossible within

**parentheses first**, then

**exponents**,then multiplication and division (from left to right), and thenaddition and subtraction (from left to right).

## What is the quotient rule for exponents?

**exponents**with a base of ten,we will use the

**quotient rule**. This

**rule**states thatwhen you are dividing two

**exponents**with the same base, youmust subtract the

**exponents**.

## What are the three rules of exponents?

**RULES**.

**Rule**1: To multiplyidentical bases, add the

**exponents**.

**Rule**2: To divideidentical bases, subtract the

**exponents**.

**Rule 3**: Whenthere are

**two**or more

**exponents**and only one base,multiply the

**exponents**.
