Question

Simplify :

$22.32\times 0.752\left\{\left(11.232-\overline{2.39+17.09\times 2}\right)\times \sqrt{144}of\frac{4}{7}\right\}$

Answer 1

We have,

$$\begin{gathered} =22.32\times 0.752\left\{\left(11.232-\overline{2.39+17.09\times 2}\right)\times \sqrt{441}of\frac{4}{7}\right\} \\ =22.32\times 0.752\left\{\left(11.232-\overline{2.39+34.18}\right)\times 21of\frac{4}{7}\right\}\left[\sqrt{441}=21\right] \\ =22.32\times 0.752\left\{\left(11.232-36.57\right)\times 21\times \frac{4}{7}\right\} \\ =22.32\times 0.752\left\{\left(-25.338\right)\times 12\right\} \\ =22.32\times 0.752\left\{-304.056\right\} \\ =16.78464\times \left\{-304.056\right\} \\ =5,103.4705 \end{gathered}$$

Hence, the required answer is $5,103.4705$.
