Best ResponseYou've already chosen the best response.1hmmm... it is much long and complicated. Do you know what is factorial?

Best ResponseYou've already chosen the best response.0If I were to expand (3t)^3 is it 3^3+3(3^2t)+3(3t^2)t^2

Best ResponseYou've already chosen the best response.1here your brackets are wrong. they should look like this. 3(3^2)t and 3(3)t^2

Best ResponseYou've already chosen the best response.1ok. it will take much time. let us start. do you know the formula (a+b)^2=a^2+2ab+b^2

Best ResponseYou've already chosen the best response.1good. it is also a binomial theorem. Notice that here power two indicates that when we expand our formula, we get one more term than the no. of exponent. Here exponent is 2 while when we expanded then we got 3 terms.

Best ResponseYou've already chosen the best response.1similarly, I hope you know the formula (a+b)^3=a^3+3a^2b+3ab^2+b^3 here exponent is 3 while expanded terms are 4. This implies that expanded terms will always be one more than the exponent. Now is it clear?

Best ResponseYou've already chosen the best response.1welcome. ok now make a step ahead. here is binomial formula. \[(a+b)^{n}=C _{0}^{n}a ^{n}+C _{1}^{n}a ^{n1}b+C _{2}^{n}a ^{n2}b ^{2}.....\] Where C stands for combination. in general this combination is written as, \[C _{r}^{n}=n!/(r!(nr)!)\] now in above formula is constantly increasing, r=0,r=1,r=2.......
