Powers And Roots
Muhtasari
Powers and roots give you a compact way to express repeated multiplication and to reverse it. From squaring a side length to find an area, to using index laws to simplify algebraic expressions, these skills run through almost every topic in the Edexcel IGCSE specification.
You will build fluency with squares, cubes and their roots, master the index laws for integer powers, and learn to decompose numbers into prime factors for finding HCF and LCM. Higher tier students will extend this to surds and fractional indices.
Malengo
- Identify square numbers and cube numbers

- [Higher] Understand the meaning of surds
- [Higher] Manipulate surds, including rationalising a denominator
- [Higher] Use index laws to simplify and evaluate numerical expressions involving integer, fractional and negative powers
