simplify.\n\\sqrt{18}

Explanation:

Step1: Factorize the number inside the square root

Factorize (18) as (9\times2), so (\sqrt{18}=\sqrt{9\times2}).

Step2: Use the property of square roots (\sqrt{ab}=\sqrt{a}\cdot\sqrt{b}) ((a\geq0,b\geq0))

We get (\sqrt{9\times2}=\sqrt{9}\cdot\sqrt{2}). Since (\sqrt{9} = 3), then (\sqrt{9}\cdot\sqrt{2}=3\sqrt{2}).

Answer:

(3\sqrt{2})
