问题描述:

有理数除法 8/(-4/9)/五分之十八 (-5/6+3/8)x(-24)
8+(-3)2次方X(-2) 100/(-2)2次方-(-2)/(-2/3) 23/{(-3)2次方-(-4)}
(3/4-7/8)/(-7/8 ) -2 2次方X3 2次方-(-2)2次方

(-5/6+3/8)x(-24)
=(-5/6)x(-24)+3/8x(-24)
=20-9
=11
8+(-3)2次方X(-2)
=8+9x(-2)
=8-18
=-10
100/(-2)2次方-(-2)/(-2/3)
=100x4-(-2)x(-3/2)
=400+3
=403
23/{(-3)2次方-(-4)}
=23/(9+4)
=23/13
(3/4-7/8)/(-7/8 )
=-(1/8)/(-7/8)
=7
-2 2次方X3 2次方-(-2)2次方
=4*9-4
=32
