计算题四道
①(2ax)^2·(-3/4a^4x^3y^3)÷(-1/2a^5xy^2)
②(21a^3-14a^2+7a)÷7a
③(24m^3n-16m^2n^2+mn^3)÷(-8m)
④(36x^6-24x^4+12x^3)÷12x^2

①(2ax)^2·(-3/4a^4x^3y^3)÷(-1/2a^5xy^2)
=(-3a^6x^5y^3)÷(-1/2a^5xy^2)
=6ax^4y
②(21a^3-14a^2+7a)÷7a
=3a^2-2a+1
③(24m^3n-16m^2n^2+mn^3)÷(-8m)
=-3m^2n+2mn^2-1/8n^2
④(36x^6-24x^4+12x^3)÷12x^2
=3x^4-2x^2+x

1、=6 a x^4 y
2、=3a^2 -2a +1
3、= -3m^2n +2mn^2 -(n^3)/8
4、=3x^4 -2x^2 +x

没分啊兄弟
