What is the square root of eighty one?
Square root of 81 has two solutions: SQRT(81) = +9 and -9 SQRT(81) = +9. The square root function has just a single output for every input. It, by definition, returns the positive 2nd root of the function. So SQRT(x) is always non-negative. This is distinctly different than saying, "what number squared equals 81?" That refers to solutions to the equation x^2 = 81, of which there are two.....+9 and -9.
