整式的除法计算
1.(-3/2)^0/(-3/2)^2
2.(-2ab)^5/ab^4
3.(2x^2y)^3*(-7xy^2)/(14x^4*y^4)
4.(3/2)(2a+b)^3/(2/3)(2a+b)^2
答
1.(-3/2)^0/(-3/2)^2＝(-3/2)^﹙﹣2﹚＝﹙﹣2/3﹚^2＝4/92.(-2ab)^5/ab^4＝﹣32a^5b^5÷ab^4＝﹣32a^4b3.(2x^2y)^3*(-7xy^2)/(14x^4*y^4)＝8x^6y^3*(-7xy^2)÷14x^4y^4＝﹣4x^3y4.(3/2)(2a+b)^3/(2/3)(2a+b)^2＝9/4...(-ab)^5/ab^4怎么做?(-ab)^5/ab^4＝-a^5b^5÷ab^4＝﹣a^4b(-ab)^5/﹙ab﹚^4＝﹣﹙ab﹚^5÷﹙ab﹚^4＝﹣﹙ab﹚^1＝﹣ab
