计算题:(-3x^2y^3+6x^2y^2-1/3xy)÷(-1/3xy)

计算题:(-3x^2y^3+6x^2y^2-1/3xy)÷(-1/3xy)
计算题:(-3x^2y^3+6x^2y^2-1/3xy)÷(-1/3xy)

计算题:(-3x^2y^3+6x^2y^2-1/3xy)÷(-1/3xy)
原式=-3x^2y^3÷(-1/3xy)+6x^2y^2÷(-1/3xy)-1/3xy÷(-1/3xy)
=9xy^2-18xy+1

解(-3x^2y^3+6x^2y^2-1/3xy)÷(-1/3xy)
=(-3x^2y^3)÷(-1/3xy)+(6x^2y^2)÷(-1/3xy)+(-1/3xy)÷(-1/3xy)
=9xy^2-18xy+1

:(-3x^2y^3+6x^2y^2-1/3xy)÷(-1/3xy)
=-3x^2y^3÷(-1/3xy)+6x^2y^2÷(-1/3xy)-1/3xy ÷(-1/3xy)
=9xy^2 -18xy +1
