This is a genuinely fun one

hint 1 (don't peek unless you really need it)

spoiler

try solving a simpler version of the problem

hint 2 (supplementary to hint 1)

spoiler

the simpler version is x^x^=2

hint 3 (unrelated to 1 and 2)

spoiler

x^x*x^x^=(x^x^)^(x^x^)

hint 4 (its basically the answer)

spoiler

x^x^=e^(ln x)(e^(ln x))
