Homework Statement


(27-3y6)1/3


The Attempt at a Solution


I THINK THIS IS HOW YOU SHOULD DO THIS:
(1/273Y6)1/3

My feeling is the (1/273) should still be evaluated. Yes?

Remember that ## (a^{x})^{y} = a^{xy} ## and ## a^{-x}=\frac{1}{a^x} ##

How does this help you?

Distribute the exponent

$$(x^a \! y^b)^c=x^{a c} \! y^{b c} \\
(5^8 \! s^4)^{(1/4)}=5^{8 (1/4)} \! s^{4 (1/4)}=5^2 \! s$$
 
solution

ok.
I get y2/27
