Powers, Roots & Laws of Indices Assessment

A full assessment covering powers, roots, fractional indices, core laws of indices and mixed multi-step problems.

Questions 40
Suggested Time 50 min
Secure 80%+
Developing 60–79%
Instructions:
Answer all 40 questions. Simplify algebraic answers fully. Where a negative index appears, rewrite it using positive indices unless the question says otherwise. Work carefully: some questions require two or more laws of indices.
