RT,[4(a-b)^m-1]*[-3(a-b)^2m]好吧...我错了...应该是这样的...[4(a-b)^(m-1)]*[-3(a-b)^(2m)]RT,[4(a-b)^m-1]*[-3(a-b

RT,[4(a-b)^m-1]*[-3(a-b)^2m]好吧...我错了...应该是这样的...[4(a-b)^(m-1)]*[-3(a-b)^(2m)]
RT,
[4(a-b)^m-1]*[-3(a-b)^2m]
好吧...我错了...应该是这样的...
[4(a-b)^(m-1)]*[-3(a-b)^(2m)]

RT,[4(a-b)^m-1]*[-3(a-b)^2m]好吧...我错了...应该是这样的...[4(a-b)^(m-1)]*[-3(a-b)^(2m)]
令（a-b）^m=n
即原式=（4n-1）*（-3n^2）=3n^2-12n^3
