Is a mathematical symbol used to represent the third-level operation.

When inputting mathematical formulas on the computer, this symbol is often used to represent the power because it is inconvenient to input the power. For example, the fifth power of 2 is usually expressed as 2 5; For example, 5 2 represents the square of 5, which is the square of 5. (For the operation of the power supply, see Power Supply)

Positive integer power algorithm

The most basic definition of power is: let a be a certain number, n be a positive integer, and the n power of a is expressed as a? That represents the result of n times multiplication, such as 2? =2×2×2×2= 16。

There are two algorithms for power:

The first is to calculate directly by multiplication, such as: 3? =3×3×3×3=8 1。

The second is the multiplication of numbers under the power class, such as: 3? =9×9=8 1。
