A logarithm is basically an exponent.
If you have b to the z is equal to a, it can be rewritten as log base b of a is equal to x.
So if we want to write m to the two is equal to twenty-five, we have to think backwards.
We see that the original base becomes the base in the log, so the m will now be in the base of the log.
We also see that the exponent is what it equals so, this exponent is going to be right here,
and since a is right after the log the twenty-five will be right after the log.
So the base goes into the base. Base goes into the base,
the exponent is what it equals and twenty-five is what comes after the log.
If we want to write this as an exponent,
x becomes the base it's raised to the second power and it's equal to sixty-four.
