Question

What is the simplest radical form of the expression?

(x^4y^7)^2/3

Answer 1

x^8/3 y^14/3

Explanation:

When there are exponents inside and outside of the parenthesis, just multiply them.

for example (x^a)^b = x^(a*b)

So x^(4 * 2/3) y^(7*2/3) = x^8/3 y^14/3

Answer 2

The correct answer is D
`x^(2) y^(4) \sqrt[3]{x^(2)y^(2) }`

Explanation:

I took the test


`x^(2) y^(4) \sqrt[3]{x^(2)y^(2) }`
