We need to find the value of f(x) when x= -2

`f(x)= (x^x)^(x^-x)`

`==> f(-2)= (-2^-2)^(-2^2)`

`==> f(-2)= (-2^-2)^4`

`==> f(-2)= (-1/2^2)^4`

`==> f(-2)= (-1/4)^4`

`==> f(-2)= 1/4^4 = 1/256`

`==> `The value of `(x^x)^(x^-x)` when x= -2 is `1/256`

i think the answer for f(-2)=-(1/64) as per my calculation. If the answer is not correct then please update it below and also the method by which you have solved it.

But this answer is calculated from the given form of question.(x^x)^(x^-x) if x=-2

Otherwise I'm agree with answer mentioed above.
