Generally speaking, in mathematics, we write the product of multiplying n identical factors A as n. This operation of multiplying several identical factors is called power, and the result of power is called power. In n, a is called the base and n is called the exponent. N is pronounced "a to the n power" or "a to the n power".
A number can be regarded as the first power of the number itself. For example, 5 is 5 1, and the index 1 is usually omitted. Quadratic is also called square, for example, 5 2 is usually pronounced as "the square of 5"; Cubes are also called cubes. For example, 5 3 can be read as "5 cubes".
Extended data:
First, the definition of power
Power refers to the result of power operation. Nm refers to the result of multiplying m by n, which is called the m power of n, and also called the m power of n, where n is the base and m is the power exponent.
Second, the operation theorem of power
Homobasic power: am× an = am+n; am/an=am-n
Power of product: ambm = (ab) m.
Third, the comparison of negative exponential powers
Compared with the negative exponential power with positive radix, the larger the exponent, the greater the power.
