Adding Rational Expressions
1. 4m2/3m+2 + 6m 4/ 3m+2=

(4m2)/(3m+2) + (6m 4)/ (3m+2) = ?
Since the denminators are the same, you can add the numerators. This will result in
(10m6)/(3m+2) 
2. 9/xy^3+,  7ap/xy^3m=

Your notation "+," makes no sense. The denominator at the end is ambiguous. Learn to use parentheses. Please use a new post for new questions.
