Class 8 Mathematics — Exponents and Powers Important Questions with Answers (Long answers)
Class 8 Mathematics is the last middle-school year before Class 9 polynomials and Euclid. Rational numbers get a full number-line treatment, linear equations move beyond one-step, and mensuration adds cubes and cylinders. This bank follows the rationalized NCERT so you are not revising deleted chapters. Search terms such as “class 8 rational numbers important questions” and “linear equations class 8 MCQ” open the matching chip. Twenty questions a page, answers folded.
Negative exponents: a⁻ⁿ = 1/aⁿ. Scientific notation for very small and very large numbers. Laws remain the Class 7 set plus negatives. (10⁻³) is 0.001, not −1000. These MCQs punish sign errors more than memory of the law names. You are on Exponents and Powers (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order.

Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL.
