Exponents. 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: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared" Some more examples: Example: 53 = 5 × 5 × 5 = 125.

An exponent of a number shows how many times we are multiplying a number by itself. For example, 3^4 means we are multiplying 3 four times. Learn everything about exponents definition in this article.
In short, power or exponent indicates the number of times a number needs to be multiplied by itself. Here, the base can be any integer, fraction or decimal. The exponent can also take up any value, be it positive or negative.
The exponent of a number says how many times to use that number in a multiplication. It is written as a small number to the right and above the base number. In this example: 8 2 = 8 × 8 = 64. (The exponent "2" says to use the 8 two times in a multiplication.) Another example: 5 3 = 5 × 5 × 5 = 125.
