Exponentials & Logarithms — IB Maths AA HL Practice
Logarithms and exponentials appear on every AA HL paper. Climb from evaluating logs and the log laws to solving exponential equations and the HL 'hidden quadratic' in $e^{x}$ — with a worked example every time you slip.
The idea
What you'll master
- Evaluate a log
- Laws of logs
- Solve exponential
- Log equation
- Hidden quadratic
Sample questions
- Evaluate $\log_{3}27$.
- Find the value of $\log_{2}8-\log_{2}2$.
- Solve $3^{x}=50$, giving $x$ to 3 significant figures.
Every attempt generates new numbers — the practice below never runs out.

Frequently asked questions
Is this IB Maths AA HL exponentials & logarithms practice free?
You can read the method and try the sample questions here for free. Unlimited exponentials & logarithms practice is part of the full Photon Learning Studio — a one-time SGD 250 unlocks every topic.
How is this different from past-paper practice?
Every question is generated fresh at exam standard. When you get one wrong it re-teaches that exact skill — a hint, then a fully worked example of the same type, then a step-by-step walkthrough — so you build the method, not just memorise answers.
