What is the cube root of 192x to the 7th power?

• Math -

you have ∛(192x)^7
192 = 64*3, so ∛(192x) = 4∛(3x)

(4∛(3x))^7 = 16384 ∛(3x)7

• Math -

Hmm. I guess we could pull out some 3x stuff to get

16384 (3x)^2 ∛(3x)
= 147456 x2 ∛(3x)

simplify the expression (the 7th root of 11x/y^6)(the 7th root of y^6/11x^8) the root is over the whole fraction in both cases. I've already done the problem once and got x(the 7th root of 1/x). which apparently this is wrong.
