Question
11 simplify the radical. drag your answer into the yellow answer space. \\(\sqrt{20} = \\) yellow box pink arrow options: 3\\(\sqrt{6}\\), 2\\(\sqrt{5}\\), 25\\(\sqrt{5}\\), 4\\(\sqrt{2}\\), 6\\(\sqrt{3}\\), 2\\(\sqrt{4}\\), 5\\(\sqrt{3}\\), 3\\(\sqrt{3}\\), 7\\(\sqrt{2}\\), 9\\(\sqrt{6}\\)
Step1: Factorizar 20
Descomponer 20 en factores, buscando un cuadrado perfecto: \( 20 = 4 \times 5 \)
Step2: Aplicar propiedad de raíces
Usar la propiedad \( \sqrt{ab} = \sqrt{a} \times \sqrt{b} \) (con \( a\geq0, b\geq0 \)): \( \sqrt{20} = \sqrt{4 \times 5} = \sqrt{4} \times \sqrt{5} \)
Step3: Simplificar \( \sqrt{4} \)
Como \( \sqrt{4} = 2 \), entonces \( \sqrt{20} = 2\sqrt{5} \)
