The **__ exponent __** of a number says **how many times** to use the number in a multiplication. In **82** the "2" says to use 8 twice in a multiplication, so **82 = 8 × 8 = 64** In words: 82 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared" // Exponents are also called __Powers or Indices__. //

Example: **53 = 5 × 5 × 5 = 125**

 * ● In words: 53 could be called "5 to the third power", "5 to the power 3" or simply "5 cubed"
 * ● In words: 24 could be called "2 to the fourth power" or "2 to the power 4" or simply "2 to the 4th"

Example: **24 = 2 × 2 × 2 × 2 = 16**
Exponents make it easier to write and use many multiplications Example: **96** is easier to write and read than **9 × 9 × 9 × 9 × 9 × 9**

How to __Square A Number__
** To square a number, just multiply it by itself ... **

Example: What is 3 squared? It is 3 X 3 = 9
__ A square root __ is working the other way. You start with the answer and work out what number has been multiplied by itself to equal it. Example: 3
