sqrt[(16x)4] = (16x)2 = 256x2
√(16x) = 4√x = 4x1/2
[(-16x)12]1/3 = (-16x)4 = 65536x4
If you square an expression and then take the square root, the squaring and the square root cancel one another, EXCEPT that the sign will be positive. Thus, if you square 16x, and then take the square root, the answer can be 16x or -16x, depending on whether "x" is positive or negative. Or if you only square x, and then take the square root of the entire expression, it would be 4x or -4x (once again, depending on whether "x" is positive or negative).
