Indices and Surds | OCR A A-Level Maths | 40 Worked Examples (H240)

Forty fully worked OCR A A-Level Maths questions on algebraic manipulation: indices and surds (spec 1.02a-b, H240), every line explained and annotated to the real OCR mark scheme (M, A, B and SC codes). The pack ramps from single-step index laws and surd simplification, through rationalising binomial denominators with the conjugate, up to detailed-reasoning proofs and disguised-quadratic index and surd equations, so it stretches a student from first contact to exam-grade fluency. Each solution breaks the working into one atomic step per line, with a plain-English note on why each move is made and where the classic traps sit, exactly the depth a learner needs to reproduce the method under pressure. Written to OCR’s own answer-format conventions: exact surd form, fully rationalised denominators and the detailed-reasoning (DR) rule where a calculator answer alone scores nothing. Progressive difficulty (16 Easy, 16 Standard, 8 Challenging). Ideal for homework, revision, cover lessons or targeted intervention. Full answers included.
