### Example Question #161 : Algebraic Concepts

Simplify:

**Possible Answers:**

**Correct answer:**

First we should simplify the first expression. We can first apply the power of a product rule and then apply the power of a power rule. So we can write:

Return to the original expression:

Since the variables have the same exponents we can write:

### Example Question #12 : Algebra

Gina's mom baked 12 cookies. 8 were cinnamon and 4 were chocolate chip. If Gina eats one of the cinnamon cookies, how many more cinnamon cookies are there than chocolate chip?

**Possible Answers:**
