\( \hspace{15em} \ = \ {a}^{3} 3{a}^{2}b 3a{b}^2 {b}^{3} \) Of course this is a really tedious way for a very large index/power/exponent number Instead of doing it manually, we could use a formula called the Binomial Theorem which is shown belowBinomial Expansion Concepts & Theory If n is a positive integer, (a x) n can be expanded as (a x) n = a n n C 1 a n1 x n C 2 a n2 x 2 n C 3 a n3 x 3 x n Applying binomial on (a b) 2 Using general expansion equation a 2 c 1 (a) 21 (b) 1 b = a 2 2ab b 2Question 10 Find the ratio of the 5 th term from the beginning to the 5 th term from the end in the binomial expansion of 2 1/3 1/{2(3) 1/3} 10 Solution Question 11 Find the coefficient of a 3 b 2 c 4 d in the expansion of (abcd) 10 Solution Binomial Theorem (a+b)^3 binomial expansion
