    not -x^4 = 256 because this -x^4 means -1(4)^4 not (-4)^4

    so -x^4 = -256 is correct right?

    @Yahoo! this is -(x^4) not (-x)^4

    because the exponent just affects the nearest base

    look his question it is just -x^4

    the ^4 is just on x...not on - too

  41. moongazer

    because -x^4 is like -1(x)^4 not (-x)^4 I think this is the explanation?

    i would say if (-x)^4=256 & -(x^4)=-256

  43. lgbasallote

    @Yahoo! (-1)(4) so -4

    -2^2 = -1 (2^2) = -1 * 4 = -4
