=0
(91*48*75)/(25*13*16)
=(7*13*16*3*25*3)/(25*13*16)
=(7*3*3)*(25*13*16)/(25*13*16)
=7*3*3

2001×200020002000-2000×200120012001
=2001×(2000×100010001)-2000×(2001×100010001)

(91×48×75)÷(25×13×16)
=((13×7)×(16×3)×(25×3))÷(13×16×25)
=7×3×3
=63
答案为:0
2001*2000*100010001-2000*2001*1001001=0
呵呵还比较简单,只要你把它分解出来就很简单啦!
