You can find that by first taking (-256) to the 1/4 power. Then just cube it.

(-256)^(1/4) is the same as [(-1)^(1/4)]*[256^(1/4)]

256^(1/4) is the square root of the square root of 256. As for (-1)^(1/4), you will have to use imaginary numbers. Sqrt(-1) = i. You will need the square root of i then. You can probably learn more about it by googling it or read on Wikipedia. Good luck!
