    Hey Patrick. I like this technique and find it really useful. I would just like to provide the explicit way of doing this derivative, using multivariable calculus, in case you or anyone else reading was curious. First you rewrite y=ln(x)^x as y=u^v, where u=ln(x) and v=x. You then use the chain rule -- ∂y/∂u(du/dx)+∂y/∂v(dv/dx) -- and you will find your derivative to be ln(x)^(x-1)+ln(ln(x)) ln(x)^x, which (after factoring out ln(x)^x) is the answer you got. Thanks for reading! :)

    but because you want all your terms in x, you sub in the value of y which would be the original question.

    This is for others who might be wondering : He isn't using the power rule. It's simply a property of logarithms. Bringing the exponent of the term that you are taking a logarithm of:
    ln(x)^10 = 10 ln(x)

    Essentially it is the product rule. If we were to use the product rule, then take the derivative of 10 is zero multiply but g(x) which is just zero+ whatever. It's faster to just kind of do that part in your head.

    @justabunga1 5 років тому

    There is another way in the second problem without using log differentiation. You can change the base ln(x) to base e. The function (ln(x))^x can be rewritten as e^(ln(ln(x))*x)=e^(xln(ln(x))). Then, differentiate this function using the chain rule and go from there. It will end up the same answer.
