Exponentiation - Wikipedia
网页In mathematics, exponentiation is an operation involving two numbers: the base and the exponent or power. Exponentiation is written as bn, where b is the base and n is the power; this is pronounced as " b (raised) to the (power of) n ". [1]
Basic rules for exponentiation - Math Insight
网页Basic rules for exponentiation. If n is a positive integer and x is any real number, then xn corresponds to repeated multiplication xn = x × x × ⋯ × x ⏟ n times. We can call this “ x raised to the power of n,” “ x to the power of n,” or simply “ x to the n.”. Here, x is the base and n is the exponent or the power.
算法学习笔记(4)：快速幂 - 知乎 - 知乎专栏
网页快速幂 （Exponentiation by squaring，平方求幂）是一种简单而有效的小算法，它可以以 O (\log n) 的时间复杂度计算乘方。 快速幂不仅本身非常常见，而且后续很多算法也都会用到快速幂。 让我们先来思考一个问题： 7的10次方，怎样算比较快？ 方法1： 最朴素的想法，7*7=49，49*7=343，... 一步一步算，共进行了 9次 乘法。 这样算无疑太慢了，尤其对计算机的CPU而言，每次运算只乘上一个个位数，无疑太屈才了。 这时我们想到，也许可以 …
Exponentiation - Properties, Definition, Formula, Examples
网页Exponentiation is a process or operation of taking the exponent of a number. If x is an integer raised to n which is a positive integer, then it can be expressed as x^n. Learn more about exponentiation in this article.
Intro to exponents (video) | Khan Academy
网页Exponents represent repeated multiplication, making numbers grow quickly. For example, 2 to the 3rd power means multiplying three 2's together, resulting in 8. This concept differs from multiplication, which is simply repeated addition. Understanding exponents is essential for mastering higher-level math.
Exponents - Math is Fun
网页The exponent of a number says how many times to use the number in a multiplication. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared". Exponents make it easier to write and use many multiplications. Example: 96 is easier to write and read than 9 × 9 × 9 × 9 × 9 × 9.
Exponentiation -- from Wolfram MathWorld
网页2024年8月22日 · Exponentiation is the process of taking a quantity b (the base) to the power of another quantity e (the exponent). This operation most commonly denoted b^e. In TeX, the Wolfram Language, and many other computer languages, exponentiation is denoted with a caret, i.e., as b^e.
