hello avinash,

yes , there is ambiguity in binomial theorem question as NTA ( also Allen ) give 10 as Answer by considering Q. as 'x' raised to the power (1/1+log x) .

But In question paper , Q. looks like 1 / ('x' raised to power 1+log x ) and on solving the question this way , no option is matching .

So , it is a problem in Question displaying .

Hence, this question should be BONUS

ALL THE BEST.
