1, the power in mathematics
Among the three meanings of power, the most important one is the power in mathematics, that is, the result of multiplication.
When m is a positive integer, n? Refers to the formula meaning m n times. When m is a decimal, m can be written as a/b (where a and b are integers), n? Represents n? Open the root number b again. When m is an imaginary number, we need to use Euler formula eiθ= cosθ+isθ, and then use logarithmic properties to solve it. Put n? As a result of power, it is called m power of n, also called m power of n.
2. The power of words.
(1) Powerhead: the headscarf of ancient women;
(2) Power holder: the official name of Zhou Li. Palm * * * towel force;
(3) Power fence: a headscarf of ancient ethnic minorities.
(4) Ascending power: In a polynomial, the terms are arranged in the order of increasing exponent of a letter, which is called the ascending power of the letter.
(5) Nilpotent: a formula that is multiplied by several times (squared) to zero.
(6) product power: product and power.
(7) Power-down: Polynomial terms are arranged in descending order of letter index, which is called power-down of the letter.
(8) Power series: an infinite series in which each term is the product of the continuous integer power of a variable and a constant.
