You can put this solution on YOUR website! You solve logarithms with exponentials, here is the relationship, assuming you mean the natural logarith of 5.
:
The base of a natural logarithm is e (the number e, 2.718...)
therefore:
log_b(x) = y
b^ŷ = x
log_e 5 = y
e^ŷ = 5
or if you want to use the numerical equivalent of e to three decimals:
2.718^ŷ = 5
There is no way other than approximation by series or
iterative methods, because it is an irrational number.

The "solution" above uses e, but there is no way to find
e other than by approximation by series or iterative
methods, because it is an irrational number. It only uses
e to 3 decimal places.

Without using a calculator, you may look to trigonometric tables
(as your grandfather and grandmother did in pre-computer era)
or to the Internet.
