Answer 1

1.а) 3(a^6)+6(b^2)-7(c^4)+2(a^6)-9(b^2) = 5(a^6)-3(b^2)-7(c^4)
б) 6a(b^6)-5(b^6)a+(c^4)-a(b^6)-9(c^4) = -8(c^4)

2. а) 12((x^4)^2)(y^4)-x(y^5)+6(((-x^2)y)^4) = 12(x^8)(y^4)-x(y^5)+6(x^8)(y^4) = 18(x^8)(y^4)-x(y^5)
б) 5(y^3)y+3(((x^3)y)^2)-3,4y(x^6)(y^8)+6(y^2)(y^2) = 5(y^4)+3(x^6)(y^2)-3,4(x^6)(y^9)+6(y^4) = -3,4(x^6)(y^9)+3(x^6)(y^2)+11(y^4)
