We can use the Product Property of Square Roots ‘in reverse’ to multiply square roots. √a · √b = √ab. Remember, we assume all variables are greater than or equal to zero. We will rewrite the Product Property of Square Roots so we see both ways together.
WebSimplifying square roots without variables Factor the radicand whenever possible. Find any factors of the radicand that is a perfect square. For example, in the expression 50 we can factor 50 such that one factor is a perfect square, that is, 50 = 25 x 2. The perfect square here is 25 because 25 = 5 5. WebTo do this simplification, I'll first multiply the two radicals together. This will give me 2 × 8 = 16 inside the radical, which I know is a perfect square. \sqrt {2\,}\,\sqrt {8\,} = \sqrt {2\times 8\,} 2 8 = 2×8 = \sqrt {16\,} = \sqrt {4^2\,} = 16 = 42 = \mathbf {\color {purple} {4}} = 4
