Algorithm of power: let a be a certain number, n be a positive integer, and the n power of a be expressed as a? That represents the result of n times multiplication, such as 2? =2×2×2×2= 16。 The definition of power can also be extended to zero power and negative power and so on.

There are also special cases of powers, such as cubes.

1 and cubes are also called cubes. The product of three identical numbers is called the cube of this number. For example, 5×5×5 is called the cube of 5, and it is recorded as 5? .

2, quantifier, used for volume, generally refers to cubic meters.

3. A cube is equal to its own number only 1, 0,-1.

4. The cube of positive number is positive number, the cube of 0 is 0, and the cube of negative number is negative number. Extension: odd powers of negative numbers are all negative numbers.

The zeroth power of any nonzero number is equal to 1. The reasons are as follows: Usually, the third power representing the third power of 5 is 125, that is, the quadratic power of 5×5×5= 1255 is 25, that is, the 1 power of 5×5=255 is 5, that is, 5× 1=5. Therefore, when n≥0, 5 will be

When inputting mathematical formulas on the computer, because it is inconvenient to input the power, the symbol ""is often used to represent the power. For example, the fifth power of 2 is usually expressed as 2 5.
