Answer 1

（6a^2b-5a^2c^2)÷(-3a^2)=-2b+5/3c�0�5；
1.（16x^4+4a^2+x）÷x=16x三次方+4a�0�5/x+1
2.（3a^2b-2ab+2ab^2)÷(ab)=3a-2+2b
3.(-4a^3+6a^2b^3+3a^3b^3)÷(-4a^2)=a-3/2b三次方-3ab三次方/4
4.（2\5mn^3-m^2n^2+1\6n^4)÷(2\3n^2)=4/15mn五次方-2m�0�5/3+1/n�0�5
5.(1\10xy^2+1\4y^2-1\2y)÷(1\5y)=1/2XY-5/2
6.[(x+1)(x+2)-2]÷x=X�0�5+3x+2-2/x=x�0�5+3X/X=X(X+3)/X=X+3.

Answer 2

1. （16x^4+4a^2+x）÷x
=16x^3+4a^2/x+1
2. （3a^2b-2ab+2ab^2)÷(ab)
=(3a^2b/ab-2ab/ab+2ab^2/ab)= (3a-2+2b)
3. (-4a^3+6a^2b^3+3a^3b^3)÷(-4a^2)
(-4a^3/-4a^2+6a^2b^3/-4ab^2+3a^3b^3/-4a^2)= {a-6/4b^3-(3/4)b^3/a^2}
4 （2\5mn^3-m^2n^2+1\6n^4)÷(2\3n^2)
={(2/5mn^3)/(2/3n^2)-m^2n^2/(2/3n^2)+(1/6n^4)/(2/3n^2)}={5/3mn-3/2m^2+1/4n^2}
5 (1\10xy^2+1\4y^2-1\2y)÷(1\5y)
={(1/10xy^2)/(1/5y)+(1/4y^2)/(1/5y)-(1/2y)/(1/5y)}=(1/2xy+4/5y-2.5}

6. [(x+1)(x+2)-2]÷x
=(x^2+3x+1)/x
=(x^/x+3x/x+1/x)
=x+3+1/x
（6a^2b-5a^2c^2)÷(-3a^2)
={6a^2b/(-3a^2)-5a^2c^2/(-3a^2)}
=-2b+5/3c^2
