Answer:
   -x^4y^2 +7x^3y^3 +2x^2y^4 -3xy^5
Step-by-step explanation:
The powers of x in the terms of the given expression are ...
   4, 3, 1, 2
so, we want to swap the last two terms to put them in the desired order:
   -x^4y^2 +7x^3y^3 +2x^2y^4 -3xy^5
 
        
             
        
        
        
1/8, 7/2, 5/6, 10/3
just swap numerator and denominator for each
