Power Property of Logarithms

The Power Property of Logarithms states that the logarithm of a number raised to a power is equal to the product of the power and the logarithm of the number. If M>0M > 0, a>0a > 0, aeq1a eq 1, and pp is any real number, then logaMp=plogaM\log_a M^p = p \log_a M. This is related to the Power Property for Exponents, (am)n=amn(a^m)^n = a^{m \cdot n}, where raising a power to a power requires multiplying the exponents. Similarly, applying the Power Property of Logarithms allows the exponent to be brought in front of the logarithm as a multiplier.
