Question

Solve:

$\frac{2}{5}x[5x\frac{7}{6}+\frac{1}{3}x\left(3x\frac{4}{11}\right)]$

Answer 1

We have,

$\frac{2}{5}x[5x\times \frac{7}{6}+\frac{1}{3}x(3x\times \frac{4}{11})]$

$\Rightarrow \frac{2}{5}x[\frac{35x}{6}+\frac{1}{3}x\left(\frac{12x}{11}\right)]$

$\Rightarrow \frac{2}{5}x[\frac{35x}{6}+\left(\frac{4x^2}{11}\right)]$

$\Rightarrow \frac{2}{5}x\left[\frac{385x+24x^2}{66}\right]$

$\Rightarrow \left[\frac{385x^2+24x^3}{165}\right]$

Hence, this is the answer.
