Question : If $2x + {\frac{2}{9x}} = 4$, then the value of $27x^3 + \frac{1}{27x^{3}}$ is:

Option 1: 180

Option 2: 198

Option 3: 234

Option 4: 252

Team Careers360 21st Jan, 2024

Correct Answer: 198


Solution : Given: $2x + {\frac{2}{9x}}= 4$--------------------------(i)
In order to bring 3 as coefficient of $x$, multiply (i) with $\frac{3}{2}$,
$\frac{3}{2}×(2x+{\frac{2}{9x}}) = \frac{3}{2}×4$
⇒$\frac{3}{2}×2x+\frac{3}{2}×\frac{2}{9x} = 6$
⇒ $3x+\frac{3}{9x} = 6$
⇒ $3x+\frac{1}{3x} = 6$-------------------------(ii)
Taking a cube on both sides of equation (ii),
$(3x+\frac{1}{3x})^{3} = 6^{3}$
Since
