What is an index or power?

An index, or power, is used to show that a quantity is repeatedly multiplied by itself. This can be done with letters as well as numbers. So, we might have: a × a × a × a × a. Since there are five a’s multiplied together we write this as ‘a to the power 5’.

What are the 3 Index laws?

Laws of indices

  • The first law: multiplication. If the two terms have the same base (in this case.
  • The second law: division. If the two terms have the same base (in this case.
  • The third law: brackets. If a term with a power is itself raised to a power then the powers are multiplied together.
  • Negative powers.
  • Power of zero.
  • Fractional powers.
