Exponents

Exponents are one of my favorite topics in math! They are interesting and FUN! I mean where else can you find a short way to write very long multiplication problems?

All exponents have two parts

• Base,

• Power

• A base and power make up the exponent. An exponent cannot be an exponent without a base AND a power. See, look on the next slide!

6² is an exponent

Number 6 is the BASE (the number being multiplied).

Number 2 is the POWER (the amount of times to use 6 in multiplication)

This means we multiply 6 times 6!

So 6² means the same as 6 times 6!

Multiple Choice

True or False: Exponents have two parts, a base and a power.

• True.

• False.

The exponent of a number tells you how many times to use that number in multiplication.

• In the exponent 8² the number 2 means to use 8 twice in multiplication. Like this: 8 x 8

• So 8² is equal to the equation 8 times 8!

• 8 x 8 is the same as 8²

Multiple Choice

Exponents are ________ multiplication.

• repeated

• multiple

• not

Multiple Choice

What expression means the same as 5⁴ ?

• 5 x 4

• 5 x 5 x 5 x 5

• 5 x 4 x 5 x 4

• 4 x 4 x 4 x 4 x 4
