Q12. Find a positive value of m for which the coefficient of in the expansion
is 6.
As we know that the general term
in the binomial expansion of
is given by
So, the general term
in the binomial expansion of
is
will come when
. So,
The coefficient of in the binomial expansion of
= 6
Hence the positive value of m for which the coefficient of in the expansion
is 6, is 4.
