Can someone please help me with this?

Answer: B and D
Step-by-step explanation:
First, solve the terms inside of the parenthesis. As a general rule, whenever you multiply two terms that have the same base, you can add their exponents.
Applying this rule, the base in the problem is 6, and the exponents are 3 and -4. The sum of 3 and -4 leaves -1. Therefore, this is one of our solutions:
When you have an exponential term raised to another exponent, you can simply multiply the exponents. In the previous solution given above, multiply -1 and -3 to get 3. Therefore our second solution is:

<h2>Hello!</h2>
The answers are:
First box: 7 times the cube of the sum of x and 8
Second box: 8 added to the cube of 7x.
Third box: 8 added to 7 and x cubed.
Fourth box: the cube of the sum of 7x and 8.
<h2>Why?</h2>We are given the expression and we need to macth to the correct verbal description, so we have:
First box:
It's 7 times the cube of the sum of x and 8
Second box:
We have that "7x" is cubed and then, added to 8, so, it's 8 added to the cube of 7x.
Third box:
We have "7" times "x" cubed and added to 8, so it's 8 added to 7 and x cubed.
Fourth box:
We have "7x" added to 8, and the expression is cubed, so, it's the cube of the sum of 7x and 8.
Have a nice day!
