Question

Square root of 11 X 2 -6 +5 (4sqaured -9)

Answer 1

Given the initial expression

`\sqrt[]{11\cdot2-6}+5(4^2-9)`

Notice that it is equivalent to

`\sqrt[]{11\cdot2-6}+5(4^2-9)=(11\cdot2-6)^{(1)/(2)}+5(4^2-9)`

Simplify as shown below

`\begin{gathered} \sqrt[]{11\cdot2-6}+5(4^2-9) \\ =(11\cdot2-6)^{(1)/(2)}+5(4^2-9) \\ =(22-6)^{(1)/(2)}+5(16-9) \\ =(16)^{(1)/(2)}+5(7) \\ =4+35 \\ =39 \end{gathered}`

Therefore, the answer is 39
