1/9 •с^2•d^3 •(-c)•3d=3/9 •(-c)^(2+1) •d^(3+1)=1/3 •(-c)^3 •d^4=-1/3 •c^3 •d^4

2.

x^2 •(-1/8)•y^2 •xy=-1/8 •x^(2+1) •y^(2+1)=-1/8 •x^3 •y^3=-1/8 •1^3 •2^3=-(2^3)/2^3 •1=-1

3.

-7/9 •ab^2 •(-3/14 •a^4 •b^7)=1/(3•2) •a^(1+4) •b^(2+7)=1/6 •a^5 •b^9

4.

(1/3 •m^3 •n^2)^4=(1^4)/3^4 •m^(3•4) •n^(2•4)=1/81 •m^12 •n^8

5.

aba^2 +b^2 •a•4a=a^(1+2) b+4a^(1+1) •b^2=a^3 •b+4a^2 •b^2=2^3 •(-1/2) +4•2^2 •(-1/2)^2=-2^2 +(4•2^2)/2^2=-4+4=0
