Index notation is a short way of writing a number being multiplied by itself several times.
The number that is being multiplied by itself is known as the ‘base’.
The number written above the base is known as the ‘index’, ‘power’ or ‘exponent’.
The index is the number of times that the base must be multiplied by itself.
53 is read as ‘5 to the power of 3’ or simply ‘5 cubed’.
