Question

21 true/false. the equation represents the simplified square root for the following non - perfect square. drag your answer into the green answer space. $3\sqrt{20} = 12\sqrt{5}$ true false drag answer here!

Explanation:

Step1: Simplificar $\boldsymbol{3\sqrt{20}}$

Factorizar 20 en factores perfectos cuadrados y otros: $20 = 4\times5$. Entonces, $\sqrt{20}=\sqrt{4\times5}$. Usando la propiedad $\sqrt{ab}=\sqrt{a}\times\sqrt{b}$ (para $a,b\geq0$), tenemos $\sqrt{4\times5}=\sqrt{4}\times\sqrt{5}=2\sqrt{5}$. Multiplicando por el coeficiente 3: $3\times2\sqrt{5}=6\sqrt{5}$.

Step2: Comparar con $\boldsymbol{12\sqrt{5}}$

El valor simplificado de $3\sqrt{20}$ es $6\sqrt{5}$, que no es igual a $12\sqrt{5}$.

Answer:

FALSE
