What was the main idea of the video?

• You must have the same base in order to be able to multiply the powers.

• You must multiply the bases to multiply the powers

• You must be awake when watching a video

But what happens if there are coefficients?

Coefficients are the numbers in front of the variables.

Multiplying Exponents with Coefficients

Watch the video on multiplying exponents with coefficients.
