Exponentiation
When it is a positive integer, the exponent indicates how many copies of the base are multiplied together. For example, . The base appears times in the repeated multiplication, because the exponent is . Here, is the "base", is the "exponent", and is the "power" or, more specifically, "3 raised to the 5th power".
Elementary mathematics
Exponentiation is a mathematical operation, written as "b", involving two numbers, the base "b" and the exponent (or power) "n". When "n" is a natural number (i.e., a positive integer), exponentiation corresponds to repeated multiplication of the base: that is, "b" is the product of multiplying "n" bases:
