Answer 2

Given: The equation is$x^2=4$.

We have to find the value of$x$.

• As we know that a 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.

We are solving in the following way:

We have,

The equation is$x^2=4$.

$=>x=\sqrt{4} \\\\=>x=2\ \ ..[2\times2=4]$

Solving the above equation further we get,

The value of$x$ is$2$.

Hence, the value of$x$ is$2$.
