Indices and Scientific Notation
Use index laws only for compatible bases and maintain correct coefficient form in scientific notation.
Key ideas
- positive/negative indices
- zero exponent
- scientific notation
- orders of magnitude
- algebraic powers
Formula / rule: a^-n = 1/a^n for a≠0.
Worked example: x⁵/x²=x³.
Common trap: Do not subtract exponents when bases are different.
Key words
index — exponent
base — repeated factor
scientific notation — a×10^n
reciprocal — multiplicative inverse
order of magnitude — power-of-ten scale
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.
