The exponent of a number says how many times to use the number in a multiplication. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared" 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.
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.
Exponents An exponent is a mathematical notation that represents how many times a number, called the base, is multiplied by itself. For example, in 5 × 5 × 5, 5 is multiplied 3 times. So, in exponent form, it is written as 5 3, where 5 is the base. The number written above 5 in superscript (i.e., 3) is called the exponent.
In 1748, Leonhard Euler introduced variable exponents, and, implicitly, non-integer exponents by writing: Consider exponentials or powers in which the exponent itself is a variable.
Here you will learn about exponents, including what they are and how to write and solve equations using exponents. Students will first learn about exponents as part of numbers and operations in base ten in 5th grade, and then as part of expressions and equations in 6th grade.
Exponents, also called powers or orders, are shorthand for repeated multiplication of the same thing by itself. For instance, the shorthand for multiplying three copies of the number 5 is shown on the right-hand side of the "equals" sign in (5) (5) (5) = 53.
