In the case that you mean (-4)^{4}, it can be written out as (-4)(-4)(-4)(-4). Since multiplying two negatives gives a positive, this is equal to 16*16 = 256. More generally, (-x)^{n} for x positive and n even will always yield a positive answer.

If you mean to write -(4^{4}), the negative would stay out front:

-(4)(4)(4)(4) = -(16)(16) = -256

Luke, I think your notation is om error

-4

^{4}always means -1 * 4^{4 }You need to use parentheses if you want (-4)
