Please follow the rules of submission at this forum - enunciated at:if (81)^x=1/((125)^y) and x,y are integers then find the value of 12xy.
I think you and I were going for the same conclusion. I am waiting for OP's response!This is the second time that you have been asked to read the submission guidelines. Please do so before starting any new threads.
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

Look at response #3 -Please mention next few steps
81x=125-y⟹
81x∗125y = 1
Can x and y both be positive integers? Can they both be negative integers? Proceed
Answer is 12xy=0Look at response #3 -
what are your answers to those questions?
There you go.Answer is 12xy=0
