How do you represent the square root of 1?

Square root ( 1) = +/-1

Remember

-1 X -1 = (+)1

+1 x +1 = (+)1

So the square root of (+)1 can be either (+)1 or (-)1

However, do NOT confuse with the 'square root (-1)' . Mathematicians for centuries have been pondering over this problem, and still no answer!!!!!
