() what is the coefficient of xy^4 in the expansion of (2x+y)^5? a.2 b.5 c.10 d.40 e. it does not exist

The general term for expanding  isso for your binomial  , the general term isby inspection, we see that  has to be 4 so that the exponent on x can be 1 and the exponent on y can be 4.  so for  , use it to find the general term that has  to determine the coefficient.the coefficient of  xy^4 is  10.
