Worked examples

Logarithmic equations and inequalities

One sheet for each type of problem, with several worked examples of increasing difficulty: first the computation, then the explanation in words. Each sheet starts with links to the theory it uses.

• 1Equations with one logarithm on each side
• 2Equations with the logarithm equal to a number
• 3Equations using the properties of logarithms and by substitution
• 4Logarithmic inequalities with base greater than 1
• 5Logarithmic inequalities with base between 0 and 1
