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".
Modular exponentiation
The time required to perform the exponentiation depends on the operating environment and the processor. The method described above requires multiplications to complete.
