What to Focus On

  • Exponential notation is a short form for repeated multiplication.
  • In a^m, a is the base and m is the exponent or index.
  • The exponent shows how many times the base is multiplied by itself.

  • Prime factorisation means writing a number as a product of prime powers.
  • A natural number other than 1 has a unique prime factorisation apart from order.
  • Prime factorisation is useful in simplifying and comparing powers.

  • Same base powers are multiplied by adding exponents.
  • Same base powers are divided by subtracting exponents.
  • If the denominator exponent is larger, the answer becomes a reciprocal.

Common Mistakes to Avoid

A negative exponent makes the value negative.

a^0 is 0 for every non-zero a.

The exponent applies only to the nearest number and can be distributed across addition or subtraction.

Memory Tips

Base and exponent

Prime factorisation is unique

Law 1 of exponents: multiply same base, add exponents
