Definition of Logarithm
The logarithm \(\log_b(a) = \) asks the question, "What power must I raise \(b\) to so that I get \(a\)?"
For example, let's find \(\log_5(625)\).
The question is, what power must we raise \(5\) to so that we get \(625\)?
The answer is \(625 = 5 \times 5 \times 5 \times 5 = 5^4\). So, the answer is \(4\).
We say that the logarithm to the base \(5\) of \(625\) is \(4\), and write \(\log_5 (625) = 4\).
