Exponent is a power operation a? A parameter in (a≠0), where a is the base, n is the exponent, and the exponent is located in the upper right corner of the base. Power operation means the multiplication of the exponent base. N-power handwritten and printed characters are represented by, and the numerical or algebraic expression of the root is written in the area surrounded by the left side of the symbol and the right side of the horizontal part above the symbol, which cannot be crossed.

Mathematical explanation

Exponential function is an important function in mathematics. This function applied to the value e is written as exp(x). It can also be written as ex, where e is a mathematical constant and the base of natural logarithm, which is about equal to 2.7 1828 1828, also known as Euler number.

When a> is in 1, the negative value of exponential function to x is very flat, and the positive value to x rises rapidly. When x equals 0, y equals 1. When 0
