2-174.

Write each equation in exponential form.

1. $\log_416=2$

A log is an exponent. In this case, the exponent equals $2$.

The $4$ is the base.

$16$ is the answer to the exponential question.

$4^{2} = 16$

1. $\log6=-2$

Use the same thinking process as (a) above.

1. $\log1000=3$

This is called a 'common log'. The base is $10$.
