Power operation formula
The formula of power operation is as follows:

1, multiplication of power operation formula same base powers: a m a n = a (m+n). The same base power refers to constant base and exponential addition. For example, the cubic of 2 times the quadratic of 2 equals to the quintic of 2, because the cubic of 2 is 8 and the quadratic of 2 is 4, so 8 times 4 equals 32, that is, the quintic of 2 equals 32.

2. Power of power: (a m) n = a Mn. The power of a power means that the exponent of a power is a power and the base is unchanged. For example, the cubic of 2 times the quadratic of 2 equals to the quintic of 2, because the cubic of 2 is 8 and the quadratic of 2 is 4, so 8 times 4 equals 32, that is, the quintic of 2 equals 32. This formula can be used to quickly calculate and simplify complex mathematical expressions.

3. Division of powers with the same base: a m ÷ a n = a (m-n) (a ≠ 0). Same base powers's division means constant base and exponential subtraction. For example, the third power of 2 divided by the second power of 2 equals to the 1 power of 2, because the third power of 2 is 8 and the second power of 2 is 4, so 8 divided by 4 equals 2, that is, the 1 power of 2 equals 2.
