What are M and N in exponential logarithmic function?
In exponential function, m is the base and n is the power. In logarithmic function, m is the base and n is the real number.

According to the knowledge of high school mathematics, in the exponential function y = m n, m is the base and n is the power. In the logarithmic function y=logmn, m is the radix and n is the real number.

Function, a mathematical term. Its definition is usually divided into traditional definition and modern definition. The essence of these two functional definitions is the same, but the starting point of narrative concept is different. The traditional definition is from the perspective of movement change, and the modern definition is from the perspective of set and mapping. The modern definition of a function is to give a number set A, assume that the element in it is X, apply the corresponding rule F to the element X in A, and record it as f(x) to get another number set B, assume that the element in B is Y, and the equivalent relationship between Y and X can be expressed as y=f(x). The concept of a function includes three elements: the domain A, the domain B and the corresponding rule F, among which the core is the corresponding rule F, which is the essential feature of the function relationship.
