What is the third term in the binomial expansion of (3x + y3)4?

54x^2*y^3
18x^2*y^3
18x^2*y^6
54x^2*y^6

 that is option third is correct

Explanation:

We have been given with the expression

We have general formula for binomial expansion which is

Here

Substituting the values in the formula we will get

+----

we can clearly  see that third term of the expansion will be

Therefore, Option third is correct

answer: 7
