A "square" (2nd power) is the result of multiplying a number by itself. For example, the square of 3 is 9 because 3 x 3 = 9.
A "square root" (-2 power) is in the opposite exponential direction: you are finding the number which multiplied by itself will equal your given number. Using the same example, the square root of 9 is 3, because 3 x 3 = 9.
Except for numbers that are squares of integers, most square roots will be long non-repeating decimals. (The square root of 2 is 1.414213562...)

The difference between the square root of x and squared-?
Answer: The difference between the square root of x and squared is either x or -x. Answer: The square root is the inverse function of the square function. That means that it's basically the opposite. Asking for the square root of "x" is like asking "what number must I square to get 'x'".
What is the difference between principal square root and perfect square root?
A principal square root is any square root that's answer is positive, and a perfect square root is a square root that's answer is an integer.
The difference between variance and standard deviation?
The SD is the (positive) square root of the variance.
How do you find the distance between two points on a coordinate grid?
-- Square the difference between their 'x'-values. -- Square the difference between their 'y'-values. -- Add the two squares. -- Take the square-root of the sum. The result is the distance between the points.
What is the difference between perfect and nonperfect square roots?
Perfect square roots are square roots that have a whole number that can go into it perfectly. Nonperfect square roots are square roots that have decimal numbers going into it. Example: Perfect Square Root: 144- Square Root: 12 Nonperfect Square Root: 24- Square Root: About 4.89
