To solve the equation \(3^{(x - m)} = 5^{(x - m)}\), we can start by rewriting it as:
\[ \left(\frac{3}{5}\right)^{(x - m)} = 1 \]
This equality holds true if the exponent \((x - m)\) is zero, since any number raised to the power of 0 is equal to 1. Thus, we can set the exponent equal to zero:
\[ x - m = 0 \]
Solving for \(x\) gives:
\[ x = m \]
Thus, the solution is:
\[ \boxed{m} \]
