Question 62895
Find the third term in the expression of (3t+4)^8  choices are:

answer is 326,592t^6

Third term is given by, {(8*7)/(1*2)}(3t)^8-2 * (4)^2, which gives the value after simplification.


More:

Fourth term is given by {(8*7*6)/(1*2*3)}(3t)^8-3 * (4)^3

Fifth term is given by,   {(8*7*6*5)/(1*2*3*4)}(3t)^8-4* (4)^4

You could apply the same procedure for calculating any term in the expansion.
