一、区别1.定义不同:平方根:如果一个数x的平方等于a,即x2=a,那么这个数就叫做a的平方根,也叫做a的二次方根;算术平方根:正数a有两个平方根,其中为正的平方根叫做a的算术平方根,0的算术平方根是0.2.个数不同:一个正数有两个平方根,而一个正数只有一个算术平方根。3.表示方法不同:
First, the difference 1. Definition of different: Square root: If a number of squared x is equal to a, that is, x2 = a, then the number is called the square root of a, also known as the root of a square; Arithmetic square root: Square root, where the positive square root is called the arithmetic square root of a, and the arithmetic square root of 0 is 0.2. The numbers are different: a positive number has two square roots, and a positive number has only one arithmetic square root. 3. Different means:
