What indices show

Three-panel diagram showing x^3 times x^2 gives x^5, x^5 divided by x^2 leaves x^3 by cancellation, and (x^2)^3 expands to x^6

A power is a short way to write repeated multiplication. For example, $43=4×4×44^3 = 4 \times 4 \times 4$ , so the base is 4 and the index is 3.

Indices

Step-by-step lessons covering Oxford AQA IGCSE Maths Indices for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
