What is the 4th term in the binomial expansion of (a+b)^6)?

a.20a^3 b^3
b.20a^2 b^4
c.15a^3 b^3
d.15a^4 b^2

option A) that is 20a^3 b^3

Step-by-step explanation:

Given in the question the equation,

(a+b)^6

Formula for binomial expansion up to 4th term of  (a+b)^6)

    1st term             2nd term          3rd term             4th term

6C0 (a)^6(b)^0 + 6C1 (a)^5(b)^1 + 6C2 (a)^4(b)^2 + 6C3 (a)^3(b)^3 +

Hence, the 4th term in the binomial expansion of  (a+b)^6 = 6C3 (a)^3(b)^3

                                                                                                 = 20 (a)^3(b)^3

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
