Question

Which of the following interpretations for the given expression is correct? the cube of the difference of 5 times the square of y and 7 divided by the square of 2 times y the difference of the cube of 5 times the square of y and 7 divided by 2 times the square of y the cube of the difference of the square of 5 times y and 7 divided by the square of 2 times y the cube of the difference of 5 times the square of y and 7 divided by 2 times the square of y

Answer 1

I’ll give the expression for each option. Pick whichever matches the given expression:

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

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

 

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

 $\frac{(5y^{2})^{3}-7}{2y^{2} }$

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

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

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

(5y2-7)3/2y2

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