Logarithms: WAEC Mathematics Past Questions and Answers

What the WAEC syllabus covers in Logarithms

Our summary: Logarithms as the reverse of powers, and using their rules to simplify calculations.

• Relationship between indices and logarithms, e.g. $y = 10^k$ implies $\log_{10} y = k$
• Basic rules of logarithms e.g. $\log_{10}(pq) = \log_{10}p + \log_{10}q$, $\log_{10}(p/q) = \log_{10}p - \log_{10}q$, $\log_{10}p^n = n\log_{10}p$
• Use of tables of logarithms and anti-logarithms
