WebBasically, you need to start over, and find the derivative of f (x) = x^u, where u is some function of x, and you will find d/dx (x^u) = x^u (ln (x) (du/dx) + u/x). So you find out, shockingly, that the 1 in the derivative was not really a 1! It was (exponent/base) which only becomes 1 when the exponent and base are both x!
