解答
依题意得M=(4a
2
b-3ab
2
)÷(-4a+3b),
=ab(4a-3b)÷[-(4a-3b)],
=-ab.
故选B.

观察一列单项式:a,-2a平方,4a立方,-8a四次方,...根据你发现的规律,第7个单项式为 ,第n个单项式为 (n是正整数)
如果(4a2b-3ab2)÷M=-4a+3b,那么单项式M等于( ) A.ab B.-ab C.a D.-b
如果(4a2b-3ab2)÷M=-4a+3b,那么单项式M等于( ) A.ab B.-ab C.a D.-b
若(8a的平方—6ab的平方)/M=-4a+3b,那么单项式m=?
单项式5a2b,3ab2,-6a2b的和与-4a2b的差是_.
