To evaluate this, consider the base and argument of the logarithm. The base of the logarithm is 2. And the 8 can be expressed in terms of factor 2. So factoring 8, the expression becomes:
Then, apply the negative exponent rule .
To simplify this further, apply the logarithmic rule .
Take note that when the base and argument of a logarithm are the same, the resulting value is 1 .
Therefore, .
