##### 1 Answer

#### Explanation:

This may seem like a complicated problem due to all the variables and exponents. But, it's not.

Let's start with the original problem:

Let's first use the Distributive Property to simplify things a little bit:

We can then use some rules about multiplying together exponents with the same base as well as negative exponents to simplify a little bit more:

1)

2)

3)

Let's take care of the left side of the expression first:

Now let's work on the right side:

After all that, let's put them together, while not forgetting the

And, you're done!
