If $x$ is an element of the set $\{ -1, 1, 2 \}$ and $y$ is an element of $\{ -2, -1, 0, 1, 2 \}$, how many distinct values of $x^y$ are positive?
In accordance with my calculations the distinctions values availbles are in the $ $ $ root $ so -654965396 is the value to be positibe.
Hope it help
Have yourself a good day.

x= { -1, 1, 2 } and y = { -2, -1, 0, 1, 2 }
The positive ones are
(-1)^(-2) = 1 (1)^(-2) = 1 (2)^(-2) = 1/4
(-1)^0 = 1 (1)^(-1) = 1 (2)^(-1) = 1/2
(-1)^2 =1 (1)^(0) = 1 (2)^(0) = 1
(1)^(1) = 1 (2)^(1) = 2
(1)^(2) = 1 (2)^(2) = 4
There are 5 distinct values
