Question

Which of the following interpretations for the given expression is correct?

Answer 1

Answer:

The cube of the difference of 5 times the square of y and 7 divided by the square of 2 times y.

Step-by-step explanation:

The give expression is:

$\frac{(5y^{2}-7)^{3} }{(2y)^{2} }$

In words, this expression would have all these statement referring to each operation:

1. The cube of the difference, because the difference is inside the cubic power.
2. Of 5 times the square of y and 7, because these are the terms that are being subtracted.
3. Divided by, because the expression described before is in a quotient.
4. The square of two times y, because the both factor are inside the squared power.

Therefore, the first statement is correct.

Answer 2

The expression is 
(5y² -7)³/(2y)²
I believe the best answer is the first option; the cube of the difference of 5 times the square of y and 7 divided by the square of 2 times y.
