# Topic 1

# Topic 1 what are exponents and powers and when to use them.

## What are Exponents called?

Exponents are the same thing as powers. We say power because we won't say 2 to the exponent 3. So that why people call it to the power of.

## What are Exponents/powers?

Exponent and powers tell how many times to multiply a base number by it self. EX: 5 to the power of 3, is equal to 5x5x5. Never do 3x3x3x3x3, if you reverse it you will get the wrong answer. that

## What is a base number?

A base number is a number that is the original number. EX: 5(base) to the power of 3(exponent), the number will always be the base number.

## When to use powers/exponents?

We use powers and exponents for several things. For EX: If a tree grew 3 branches and each branch grows 3 branches how many branches will be in total in 6 days. Then you would use the exponents. It will be 3 to the power of 3 which will be 3x3x3x3x3x3 which is equal to 729. To solve exponents in 6th grade and under just multiply them normally.

## Just for a better understating.

here is another example 3 to the power of 4. What you will do is 3x3=9 x3=27 x3 = 81.

## How to write exponents?

### Common

### For example

4 is base number and 3 is exponent.
