Question

Which expression is equivalent? Please help!!!!

Answer 1

x/2y²

Explanation:

What is the cube root of 27?

3. because 3x3x3 = 27.

What is the cube root of 216?

6. because 6x6x6 = 216.

For the 3 on the right side, since it's a power or an exponent, we just divide by 3. Same thing for the 6 in the right.

Now, we have 3x/6y².

We need to simplify.

The GCF of 3 and 6 is 3, because 3 is the highest number that can be divided by both 3 and 6 while the results are whole numbers.

3/3 = 1

6/3 = 2

x/2y² is the answer.

Answer 2

2) x/ 2y^2

Explanation:

1) reduce the fraction:

27x^3 -----> x^3

216y^6----> 8y^6

2) evaluate the cube root

x

------

2y^2
