The operation formula of power is 1. Same base power multiplication: a m an = a m+n.
2. The power of power: an m n = an m n.
3. the power of the product: (ab) m =a m b m
4. idempotent division: a m ÷a n =a m-n (a≠0).
a m+n =a m a n
6. One mn = (one m) n
7.a m b m =(ab) m
8.a m-n =a m ÷a n (a≠0)
The power of the same base number a m a n =a m+n (m m, N is a natural number).
1. Define the meanings of three basic concepts: base, exponent and power.
2. Its premise is "the same base", and the base can be a specific number or letter, or a monomial or polynomial. 3. Exponents are all positive integers.
This rule can be extended to three or more times of the same base power multiplication.
5. Don't confuse it with algebraic addition. Multiplication only requires the same radix and can be calculated according to the law, that is, exponential addition with the same radix.
