Questions tagged [exponent]

Exponentiation is a mathematical operation, written as b raised to the power of n, involving two numbers, the base b and the exponent (or power) n.

Exponentiation refers to the mathematical operation involving two numbers, one is a base and another is an exponent. It is repeated multiplication. To calculate 53 you have to multiply the number 5 (base) by itself 3 times (exponent).
