SOLUTION: I need help writing a binomial expansion for this expression... (m+n^2)^4 Thank you in advance to anyone that can help me.

To reduce confusion, let .





So the problem becomes 





Write out the first 5 rows of Pascal's triangle (rows 0 through 4):





          1

         1 1

        1 2 1

       1 3 3 1

      1 4 6 4 1





The last row gives us the coefficients.



The exponent on m will start at 4 and decrease by one each term,

and the exponent on p will start at 0 and increase by 1 each term.













Now go back and replace  with
