Indices or Powers Indices or powers show how many times a number is multiplied by itself. 13³ means 13 x 13 x 13.

We know that:      5 × 5 = 25The product 5 × 5 can be written as 52. 5 × 5 is known as the expanded form (or factor form) of 25 and 52 is known as the index form of 25. Generally when a number is multiplied by itself any number of times, the expression is simplified by using the index notation. Note: 2 is called the base. 3 is called the index or power (or exponent) because it indicates the power to which the base, 2, is raised. 8 is the basic numeral (or number). 23 is read as '2 to the power 3' or simply '2 cubed'.
