let 3 sign a and 2y sign b so than in this case you can writing that (a+b)^5 =(a+b)^2 *(a+b)^3 yes ?

so than your exersice will be (3+2y)^5 =(3+2y)^2 *(3+2y)^3 so what you hope so much that  can end it easy ,because you know the formula (a3b)^2 = ??? and formule for (a+b)^3 = ??? ok ? i think that this formules you have learned in your schooles till today ok ?

It will be \[a3^0(2y)^5+ba3^1(2y)^4+ca3^2(2y)^3+da3^3(2y)^2+ea3^4(2y)^1+fa3^5(2y)^0\]

Due to the symmetry of binomial expansion, a=f, b=e and c=d. To find what they ARE without bruteforcing your way expanding the brackets, look at the 5th (as it was ^5) row of Pascal's triangle.
