You can put this solution on YOUR website! I am unsure how to solve when only using positive
:
To make a negative exponent positive, just write the reciprocal of it = x^2 * y^2
;
Would you like to prove this to yourself?
Let x=2; y=3: and
on a good calc enter: 2^2/3^-2 = 36
then enter: 2^2 * 3^2 = 36
