•2)15m^5n^4
•3)

Answer 2

Answer:

a) 4a^2-3a-a^2+11a

= 4a^2-a^2-3a+11a

= 3a^2+8a

b) 2m^2n+5n^2m+8nm^2

= 2m^2n+8nm^2+5n^2m

= 10m^2n+5n^2m

c) 21a^3b^2-14a^2b^3+9b^3a^2-18b^2

= 21a^3b^2-5a^2b^3-18b^2

d) 6mn+4m^2-7nm

= 6mn-7nm+4m^2

= -nm+4m^2

= 4m^2-nm

e) -a^2b-ba^2+7a^b

= -a^b+7a^2b-ba^2

= 6a^2b-ba^2

= 5a^2b

f) 3a+b-7b-2a

= 3a-2a+b-7b

= a-6b
