Question

Evaluate the expression. $4\left(\sqrt{\frac{147}{3}}+3\right)$

Answer 1

Evaluate the given expression

$$\begin{gathered} 4\left(\sqrt{\frac{147}{3}}+3\right)=4(\sqrt{49}+3) \\ =4(7+3)(\because \sqrt{49}=7) \\ =4\left(10\right) \\ =40\mathbf{}\mathbf{}\mathbf{} \end{gathered}$$

Hence, $4\left(\sqrt{\frac{147}{3}}+3\right)=40$.
