Let us see the solution of -1 base to power 2 and 3.

We know that 2 (-1) = 1 And 3 (-1) = -1

therefore -1 to any EVEN power answer will 1 and -1 to any ODD power answer will -1. By putting this rule to all integers. We get ...

_ n | (-1) = 1 if n is EVEN | n > (-1) = -1 if n is ODD | _|

Final answer will be 1 when n is EVEN and -1 when n is ODD.
