Question

What is the square root of \[200\] ?

Answer 1

Hint: Square Root: A square root of a number is a value that can be multiplied by itself to give the original number. It is a function of $ y = \sqrt x $ . The principal square root is the positive number square root. Unless “the square root of a number refers only to the principal square root. The square root is usually denoted as $ '\sqrt {} ' $ and it is known as a radical symbol.

Complete step by step solution:
Given,
First of all we have to factorize the number \[200\] ,
 $ \Rightarrow 200 = 2 \times 2 \times 2 \times 5 \times 5 $
Now we have to make the set and take out the radical.
The square root of given number is,
 $ = \sqrt {200} $
by factrosing it,
 $ = \sqrt {25 \times 8} $
 $ = \sqrt {5 \times 5 \times 2 \times 2 \times 2} $
Now make the set and take out from the radical.
 $ = 5 \times 2\sqrt 2 $
 $ = 10\sqrt 2 $
So, the correct answer is “ $ 10\sqrt 2 $ ”.

Note: The square root property is the one method to solve the quadratic equations. The method is generally used in equations that have the form $ a{x^2} = c $ or $ {(ax + b)^2} = c $ the equation which can be expressed on either of those forms. We can take square roots from both sides. The square root of a negative number is known as a complex number.
