Explanation:
A square root of a number n is a number x such that $x^{2} = n .$
Note that,if x is real number then $x^{2} \geq 0$
The square root of a number is that number which, when multiplied by itself will equal the original number.
To find the square root of a number, find its prime factors.
$49 = 7 \times 7$
$\Rightarrow \sqrt{49} = \sqrt{7 \times 7} = \sqrt{7^{2}}$
A square root can also be a negative number,
Not only is 7 an answer because $7 \times 7 = 49$
but also -7 is an answer because $- 7 \times - 7 = 49 .$
So, ultimate answer will be $7 & - 7$ both.
