Logarithms & Exponentials | 25 Worked Examples | Edexcel A-Level Maths

25 progressive Edexcel A-Level (9MA0) logarithms and exponentials questions with full mark-scheme style worked solutions.

What’s inside:
Easy: applying the log laws, switching between exponential and logarithmic form, solving basic equations of the form a^x = b using ln.
Medium: differentiating and integrating e^x and ln x, exponential growth and decay models N = N0 e^(kt), reducing relationships to linear form for log-log and log-linear graphs.
Hard: half-life and rate problems, combining exponential models with simultaneous equations, harder equation solving with logs on both sides and disguised exponentials.

Every solution shows every step, with M1 (method), A1 (accuracy) and B1 (independent) marks annotated at exactly the point each would be awarded. Typeset in LaTeX for clean mathematical notation.

Ideal for: Year 13 students sitting Edexcel A-Level Mathematics (9MA0) Paper 1 / Paper 2 Pure, plus tutors and teachers building targeted practice. Print-friendly, hand straight to students.
