Multiplying Surds $$\sqrt{a}\times\sqrt{b}=\sqrt{ab}$$ $$\sqrt{a}\times\sqrt{a}=a$$ $$\sqrt{a}^2=a$$ worked examples Simplify √3 × √3.  = √9 = 3 multiply the things in the surds togetther as a single surd and then simplify. Simplify √3 × √5. $$=\sqrt{3\times5}$$ = √15 multiply the surds together and if they can't be simplified, then [...]
