(-1/2011)的五次方/-(1/2011)的四次方 (-7/6-7/8)/7/12+10/3

(-1/2011)的五次方/-(1/2011)的四次方 (-7/6-7/8)/7/12+10/3
(-1/2011)的五次方/-(1/2011)的四次方 (-7/6-7/8)/7/12+10/3

(-1/2011)的五次方/-(1/2011)的四次方 (-7/6-7/8)/7/12+10/3
1、 (-1/2011)^5=-1/(2011^5)
(-1/2011)^4= 1/(2011^4)
原式=[-1/(2011^5)] / [1/(2011^4)]
=-(2011^4) / (2011^5)
=-1/2011
2、 原式= (-7/6-7/8)* (12/7) +10/3
= -2-3/2+10/3
=-1/6
