Chapter 12 - Exponential Functions and Logarithmic Functions - 12.3 Logarithmic Functions - 12.3 Exercise Set: 24

$0$

Work Step by Step

The logarithm of 1 to any valid base is zero. Hence, the given expression, $\log_9 1 ,$ is equal to $0 .$ We can check that this is true: $9^?=1$ $9^0=1$ Because $9^0=1$, the answer that we found above is correct.
