if (81)^x=1/((125)^y) and x,y are integers then find the value of 12xy.

Hint:

(81)^x=1/((125)^y)

(3)^(4x) = (5)^(-3y)

I did not find Subhotosh's hint penetrated my frequently dim, and certainly insufficiently caffeinated, mind. So here is a different hint.

[MATH]81^x = \dfrac{1}{125^y} \implies 81^x * 125^y = 1.[/MATH]
Can x and y both be positive integers? Can they both be negative integers? Proceed

I think you and I were going for the same conclusion. I am waiting for OP's response!
