Multiplying Numbers with Exponents

When multiplying bases the exponents can be added.

For example:

2^2 x 2^3

Step 1- Find exponents (2 & 3)

Step 2- Add exponents (2 + 3=5)

Step 3- Put in Exponential form (2^5)

Dividing Numbers with Exponents

When dividing numbers with exponents you keep the base and subtract the exponents.

For example:

2^5 / 2^2 = 2^5 / 2^2

Step 1- Find exponents (5 & 2)

Step 2- Subtract exponents (5-2=3)

Step 3- Put in Exponential form (2^3)
