Question

Describe Solving Square Roots

Answer 1

Describing Square roots with Examples:

Square root of a number is a value, which on multiplication by itself gives the original number. The square root is an inverse method of squaring a number. Hence, squares and square roots are related concepts.

Suppose, $x$ is the square root of $y$, then it is represented as$x=\sqrt{y}$ or we can express the same equation as$x^2=y.$ Here,’$\sqrt{}$’is the radical symbol used to represent the root of numbers. The positive number, when multiplied by itself, represents the square of the number. The square root of the square of a positive number gives the original number.

For example, the square of$3\mathrm{is}9,3^2=9$ and the square root of$9,\sqrt{9}=3$. Since $9$ is a perfect square, hence it is easy to find the square root. But for an imperfect square like $3,7,5$, etc., we have to use different methods to find the square root.
