Square root of a number is an inverse operation of squaring a number. The Square of a number is the value of power 2 of the number, while the square root of a number is the number that we need to multiply by itself to get the original number. If ‘a’ is the square root of ‘b’, it means that a×a=b.

How do you find the square root of an algorithm?
To find the square root of S, do the following:
- Make an initial guess. Guess any positive number x0.
- Improve the guess. Apply the formula x1 = (x0 + S / x0) / 2. The number x1 is a better approximation to sqrt(S).
- Iterate until convergence. Apply the formula xn+1 = (xn + S / xn) / 2 until the process converges.

What is meant by root in maths?
root, in mathematics, a solution to an equation, usually expressed as a number or an algebraic formula.This number—the (principal) nth root of a—is written n √ a or a1/n. The integer n is called the index of the root. For n = 2, the root is called the square root and is written Square root of√ a .
How do you introduce square roots and squares?
The square root of any number is equal to a number, which when multiplied with the same number gives the original number. We get perfect square roots for a perfect square number. A square root is represented by a √ sign. If x2 is a square number then x is a square root of it.
Can the square root of 180 be simplified?
180 is not a perfect square as √180 = 6√5. The square root of 180 cannot be expressed as a whole number; it can only be expressed as a non-terminating decimal. Therefore, √180 is an irrational number.

What is the square root of 800 simplified?
20 √2
What is the Square Root of 800 in Simplest Radical Form? We need to express 800 as the product of its prime factors i.e. 800 = 2 × 2 × 2 × 2 × 2 × 5 × 5. Therefore, √800 = √2 × 2 × 2 × 2 × 2 × 5 × 5 = 20 √2. Thus, the square root of 800 in the lowest radical form is 20 √2.
