Hii if sqroot(x^2)=81 then should I just take absolute square root that is 81 only or should I take 81 and -81 if the question type is QC

if it’s given \sqrt{x^2} = 81 then x = 81

if it were given the other way x^2 = \sqrt{81} then x = \pm 3

@FoxxKnight thanks a lot *±9

It will be \pm 3 as

x^2 = \sqrt{81} \\ x^2 = 9 \\ x = \pm 3
