# Math Help - Indices based problem

1. ## Indices based problem

I have thought about it and see no logical way to solve it due to not seeing a relation between the m and y and n and x.

if then show that xyz = 1

2. This is a neat problem. From the given:
$m^y=a^{xy}~\&~n^x=a^{xy}$ so $m^x\cdot n^y=a^{2xy}$

Therefore, $a^{2}=(m^x\cdot n^y)^z=a^{2xyz}$.

You finish.
