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.

Be sure to use headphones or earbuds.

Multiple Choice

Multiply:

$$5k^3\ x\ 7k^6$$  

• $$12k^9$$

What happens when you have different bases and you are multiplying?

Look to the right at the picture.  Gather all the like bases and do as you did before.
