This theorem says that, if we have an exponential operation, and the exponent is a logarithm, and the bases are the same, then the output is the log input.

For example:

2(log28) = 8

We can confirm this by evaluating the logarithm on the left. We know that:

log28 = 3

Using substitution:

2(log28) = 23

We also know that:

23 = 8

Thus:

2(log28) = 8
