👉 In mathematics, an exponentiation is a mathematical operation that involves a number (the base) raised to another number (the power). This operation is fundamental in many areas of mathematics and science. An exponential function is defined as a function where the input (the independent variable) is multiplied by itself repeatedly until it reaches the output (the dependent variable). For example, the exponential function y = b^x, where x is an exponent, has the value y when x = 1. Here
