In mathematics, exponentiation is an operation involving two numbers: the base and the exponent or power. Exponentiation is written as b n, where b is the base and n is the power; often said as "b to the power n ". [1]
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.
Learn how to simplify expressions with exponents using different rules, such as product, quotient, zero, negative, and power of a power. See examples, definitions, and a chart of exponent rules.
Learn how to represent large or small numbers using exponents and powers, and how to apply the laws and rules of exponents to simplify expressions. See solved examples, applications and video lesson on exponents and powers.
Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the second power", "8 to the power 2" or simply "8 squared" Try it yourself: So an Exponent saves us writing out lots of multiplies! Example: a7.
A power is the small floating number that goes to the right of a number or letter. For example, in the expression 3², the ² is the power. Powers activity. Play this game to see how...
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. Recommended Games. Evaluate Algebraic Expressions with One Operation Game. Play.
