Answer :
The value of square root i.e [tex]\sqrt{x^{2} }[/tex] is [tex]x[/tex].
What is square root ?
A number's square root is that portion of the number that, when multiplied by itself, yields the original number. Two unique exponents are squares and square roots.
Here [tex]\sqrt{x^{2} }[/tex] = [tex]\sqrt{x*x}[/tex] = [tex]x[/tex] because [tex]x^{2}[/tex] means product of two same number [tex]x[/tex]. So the square root of [tex]x^{2}[/tex] will be the same number which is multiplied twice i.e [tex]x[/tex].
Hence , the square root of [tex]x^{2}[/tex] is [tex]x[/tex].
