✔ 最佳答案
(-1331)/(-11)2次方 = (-1331)/(121)
= -11
[(-3)(-2)(-4]/(+3)(-2)(+4)]
= [-24]/[-24]
= 1
[(-8)*(+5)]/[(+8)-(+5)]
= [-40]/[8-5]
= -40/3
= 13.33
(其實, 你有無打錯左第三條式呀?)

1.)(-1331)/(-11)2次方
=(-1331)/(+121)
=(-11)
2.)[(-3)(-2)(-4]/(+3)(-2)(+4)]
=(-24)/(-24)
=(+1)
3.)[(-8)*(+5)]/[(+8)-(+5)]
=(-40)/(+3)
=(-13又3分之1)
=(-1331)/(+121)
=(-11)
2.)[(-3)(-2)(-4]/(+3)(-2)(+4)]
=(-24)/(-24)
=(+1)
3.)[(-8)*(+5)]/[(+8)-(+5)]
=(-40)/(+3)
=(-13又3分之1)
