# What is the opposite of squaring a number?

Subtraction is the opposite of addition, division is the inverse of multiplication, and so on. Squaring, which we learned about in a previous lesson (exponents), has an inverse too, called "finding the square root." Remember, the square of a number is that number times itself.

Regarding this, how do you undo a squared?

Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.

How do you calculate the square root of a number?

To start finding a square root via prime factorization, first, try to reduce your number into its perfect square factors.
1. Let's use an example. We want to find the square root of 400 by hand. To begin, we would divide the number into perfect square factors.
2. We would write this as: Sqrt(400) = Sqrt(25 × 16)

What is the meaning of square numbers?

In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it can be written as 3 × 3. Square numbers are non-negative.
