Powers, Factors and Roots
An exponent tells how many equal factors are multiplied. Square roots reverse squaring for non-negative values.
Key ideas
- powers
- squares
- square roots
- prime factors
- order of magnitude
Worked example: 3⁴ = 3×3×3×3 = 81.
Common trap: 3⁴ is not 3×4.
Key words
base — number being repeatedly multiplied
exponent — power showing number of factors
square — number multiplied by itself
square root — value whose square gives the number
prime factorisation — product of prime factors
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
