WebTo simplify a surd, write the number under the root sign as the product of two factors, one of which is the largest perfect square. Note that the factor 16 is the largest perfect square. Recall that the numbers 1, 4, 9, 16, 25, 36, … Web-xy must be a negative real number because x and y are both positive real numbers. On the other hand, ⁺√ (ab) = √ [ (xi)² (yi)²] = (xyi²)² = (xy)² Since ⁺√ (ab) = (xy)² and ⁺√a • ⁺√b = -xy, our problem becomes to prove that: (xy)² ≠ -xy For x, y > 0 Well this is easy!
