Simplify. Remove all perfect squares from inside the square root. V180=
inysia [295]

Answer:

6√5

Step-by-step explanation:

We have to solve the expression \sqrt{180}

Break 180 into its factors which are in the perfect square form.

Since, 180 = 9 × 4 × 5

                 = 3² × 2² × 5

Therefore, \sqrt{180}=\sqrt{3^{2}\times 2^{2}\times 5}

                           = \sqrt{3^2}\times \sqrt{2^{2}}\times \sqrt{5} [Since \sqrt{ab}=\sqrt{a}\times \sqrt{b}]

                           = 3 × 2 × √5

                           = 6√5

Therefore, solution of the given square root will be 6√5.
