The term independent of

x

\left[\sqrt{\frac{x}{3}}+\sqrt{\left(\frac{3}{2 x^2}\right)}\right]^{10}

View answer and explanation

Correct option: D

None of these

Option D (None of these) is correct because the term independent of

x

requires the power of

x

to be zero, but the resulting value of

r

is not an integer, meaning there is no constant term.
