What to Focus On

  • x^n means x multiplied by itself n times.
  • x^n is read as x raised to the power n.
  • The base is the repeated number and the exponent tells how many times it is used.
  • Product Law adds exponents with the same base.
  • Quotient Law subtracts exponents with the same base.
  • Power Law multiplies exponents when a power is raised to a power.
  • Even powers of a negative number give a positive result.
  • Odd powers of a negative number give a negative result.
  • Brackets matter when the base is negative.

Common Mistakes to Avoid

A negative base raised to zero is always negative.

A negative exponent makes the answer negative.

The Quotient Law always means subtract the exponents and write a^{m-n}.
