What is the fourth term in the expansion of (x + 4y)^4?


To find a SPECIFIC TERM of a binomial expansion, we use the formula: , where: 

                                                                      r = 4

                                                                      n = 4

                                                                      a = x

                                                                      b = 4y

We then get: 4th term of  ======>  ======>
