no, youre misunderstanding, roots of a squared number can be negative or positive, but a squared root is always positive
x^2 = 4, so x = -2 or x =2, but root[(-2)^2] and |x| = root(x^2), even though x by itself can be both negative and positive, always returns positive value, as square root returns mod of a number, learn your definitions people
