Exponentiation
Exponentiation is a mathematical operation, written as , involving two numbers, the "base" and the "exponent" . When is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, is the product of multiplying bases:
Half-exponential function
In mathematics, a half-exponential function is the functional square root of an exponential function, that is, a function "ƒ" that, if composed with itself, results in an exponential function:
