If the fourth term in the expansion of

{\left\{ {\sqrt {{x^{\left( {\frac{1}{{\log x + 1}}} \right)}}} + {x^{1/12}}} \right\}^6}

is equal to 200 and

x > 1,

, then

x

is equal to

View answer and explanation

Correct option: B

Option B (10) is correct because the value of x is found by setting the fourth term in the given expansion equal to 200 and solving the resulting equation for x, given that x > 1.
