This theorem says that, if we take the log of an exponential, and the bases are the same, then the output is the exponent.
For example:
log2(23) = 3
We can confirm this by evaluating the logarithm on the left. We know that:
23 = 8
Using substitution:
log2(23) = log28
We also know that:
log28 = 3
Thus:
log2(23) = 3

Given that:
xp = z
Prove that:
logx(xp) = p
The following properties may be helpful:
if xp = z, then logx(xp) = logxz
if xp = z, then logxz = p
if the following are true:
- a = b
- b = c
then a = c
Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
