WebbThe Product Property of Square Roots says. √ab = √a · √b. 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. WebbSo, for example, instead of √4 we prefer dealing with 2. What about roots that aren't equal to an integer, like √20? Still, we can write 20 as 4⋅5 and then use known properties to write √ (4⋅5) as √4⋅√5, which is 2√5. We *simplified* √20. Created by Sal Khan.
