Inverse Logarithms and Solving Logarithmic Equations | Year 1 Pure | A Level Maths

Treating logarithms as the inverse of exponentials unlocks a powerful technique for solving equations. In this lesson you will learn how to use log_a(x) as the inverse of a^x, solve equations of the form ln(ax + b) = q by exponentiating both sides, and combine the laws of logarithms to reduce more complex equations to a standard form. The skills developed here feed directly into solving exponential equations and exponential modelling.
