Simple...

multiplying your binomial you get a GREAT number..but....I will only list a few..and I will give you the fourth term you seek...

e^(10) + 20e^(9) f+ 180e^(8) f^(2) +960e^(7) f^(3) +3360 e^(6) f^(4)

e^(10) + 20e^(9) f+ 180e^(8) f^(2) +960e^(7) f^(3) +3360 e^(6) f^(4)

....(etc)

As you can see...the forth term is
960 e^(7) f^(3)

Thud, your answer.

Which equation represents the fourth term in the binomial expansion of (e+2f)^10
