Find the logarithm of a number, to any base.
Uses the change-of-base formula to compute a logarithm at any base from natural logarithms.
Log: logᵦ(n) = ln(n) ÷ ln(b)
What does a logarithm actually tell you?
It answers the question: what power do you need to raise the base to, to get this number? log₁₀(1000) = 3, because 10³ = 1000.
