To continue the proof of the Power Rule of Logarithms, the best step to take next is:
Simplify this equation using the Power Rule of Exponents.
This step involves manipulating the exponential equation \(mn = (b^x)^n\), which can then be simplified to \(m^n = b^{nx}\). From there, you can apply logarithmic definitions and properties to ultimately prove the Power Rule for logarithms, which states that \(\log_b(m^n) = n \cdot \log_b(m)\).
