Detail solution

  1. Don't know the steps in finding this derivative.

    But the derivative is

    (log⁡(xxx)+1)(xxx)xxx\left(\log{\left(x^{x^{x}} \right)} + 1\right) \left(x^{x^{x}}\right)^{x^{x^{x}}}

The answer is:

(log⁡(xxx)+1)(xxx)xxx\left(\log{\left(x^{x^{x}} \right)} + 1\right) \left(x^{x^{x}}\right)^{x^{x^{x}}}
