It is "raising to the power". Although repeated multiplication can be used for raising to a positive integer power
for example, a5 = a*a*a*a*a
that analogy fails for rational powers or irrational ones. And it is totally useless when the power is a complex number.
I would Say that the answer is the exponent
There isn't one. It is an algebraic operation, not an arithmetic one and is called exponentiation.
Arithmetic operators enable numeric calculations to be done. The main ones are the plus (+), minus(-), multiply(*), divide(/) and power(^).
arithmetic operator are the operator which used to perform some basic operations like addition, subtraction ,multiplication (*),division(/).
The arithmetic operator that divides contents of a cell is the front slash. =A3/B3
Arithmetic operators (+, -, *, /, % ) have greater precedence over relational operators (<, >, <=, >=, ==, !=) in C language.
arithmetic operator logic operator increment operator decrement operator conditional operator
An arithmetic operator is any of the "atomic" operators to do the following math operations: + addition - subtraction / division * multiplication % modulus division
