# Math Help - 256^(3/4)

1. ## 256^(3/4)

Trying to help a friend with some algebra 2 homework, the majority of it is very very simple but this one has me stumped how do I evaluate the 4th root of 256^3 power without a calculator or spending stupid amounts of time working it out the long way?

2. $256=2^8$

3. That really isn't very helpful to the way I view the problem but I figured it out realizing you can take the 4th root before cubing it so you get 4^3 which just equals 64.

Edit: Derp, nevermind, I just skipped the step you posted to get to the same end you would have if you had gone a step further.

The point is for you to see that it is simply $\left( 8 \right)\left( {\frac{3}{4}} \right) = 6$
