    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?

    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
