    By the power rule, you would first multiply the whole equation by the exponent, which is 0.09 so you get 0.09x^0.09. Then, you subtract the power by one, so it becomes 0.09x^(-.91).

    The derivative of a log function is the derivative of the function divided by the function itself. For example, the derivative of log(x) would be the derivative of x is 1 divided by x, and so log(x) = 1/x.

  • Question
    Isn't 1/x for positive x the derivative of ln(x)? Wouldn't the derivative of log(x) be 1/(x*ln(10)) for x>0?

    Yes , it is. The base of log(x) is log base 10, 2nd, the formula is d/dx(log_a(X) = 1/xln(a) and after substituting the value of a into the equation, we will get 1/x(ln(a)).

    d/dx(1/x) = d/dx(x^-1) = -x^-2 = -1/x^2
