Question

All real logarithms below have positive arguments and a positive base different from 1. In the power law, the argument before raising it to a power is positive.

Properties to Note:

$\log_a 1 = 0$

e.g. $\log_5 1 = 0, \log_{17.5} 1 = 0, \ln 1 = 0$

$\log_a a = 1$

e.g. $\log_{11} 11 = 1, \log_{20.5} 20.5 = 1, \ln e = 1$

Accepted Answer

$\log_a1=0$ and $\log_a a=1$
