In Binomial theorem, the expansion of the given terms and its coefficients is denoted by :

\n

$(a+bx)^n=\\tbinom{n}{0}(a)^n(bx)^{0}+\\tbinom{n}{1}(a)^{n-1}(bx)^{1}+\\tbinom{n}{2}(a)^{n-2}(bx)^{2}+...$

\n

$+\\tbinom{n}{k}(a)^{n-k}(bx)^{k}=\\sum_{k=0}^{n}{\\tbinom{n}{k}x^ka^{n-k}}$

\n

 Find the coefficient of the term indicated in the square brackets in the expansion of each of the following expressions below.]
