Power function

Exponentiation is a mathematical operation, written as b n, involving two numbers, the base b and the exponent or power n, and pronounced as b raised to the power of n . When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: = × ⋯ × ⏟. The exponent is usually shown as a superscript to the. A function $ f : x \mapsto y $ with $$ y = x ^ {a} , $$ where $ a $ is a constant number. If $ a $ is an integer, the power function is a particular case of a rational function.When $ x $ and $ a $ have complex values, the power function is not single valued if $ a $ is not an integer Power Functions AAA batterilåda.
