$\mbox{True or false:}$

$\left(54x^{-3}y^9 z^7)^{(1/3)}\, =\, 3\sqrt[3]{2}x^{-1} y^3 z^{(2/3)}$
if 7 & 2 r rite, then wat do U think?

"7 and 2"? I'm a bit confused...
The furthest I can go is $\sqrt[3]{54x^{-3}y^9 z^7}$.

I think the previous poster was referring to the powers on the variable "z". How did you do the simplification in your first post? If you could show us your steps, it will be easier to explain what is going on. Thank you!

The thing is, I didn't simplify the problem at all. It was like that originally.

Okay; then do the simplification yourself, and see if you get what they got. It would be helpful to pay particular attention to the powers on the variable "z", like the first reply suggested.
