✔ 最佳答案
y= - 1/2(2分之1)(0.5)( - y)3次方=?
=(0.5)3次方 (負負得正)
=0.625
- ( - y)3次方=?
=-(0.5)3次方
=-0.625
- y 3次方
=-0.5乘3次方 (負負得正)(正負得負)
=-0.625

1.y=-0.5.(-y)^3=(0.5)^3=0.125
2.-(-y)^3=-(-0.5)^3=0.125
.-y=--0.5^3=0.125
2.-(-y)^3=-(-0.5)^3=0.125
.-y=--0.5^3=0.125

thz..
呢D問題煩左我好耐啦><''
2008-07-18 11:30:39 補充：
-y 3次係唔係姐係:
-y x -y x -y?
姐係:
- - 1/2(- - 得正,姐係:1/2)
1/2x1/2x1/2?
係唔係咁?

(-y)3次方
=(1/2)3次方
=1/8
-(-y)3次方
=-[(1/2)3次方]
=-1/8
-y3次方
=-[(-1/2)3次方]
=-(-1/8)
=1/8
=(1/2)3次方
=1/8
-(-y)3次方
=-[(1/2)3次方]
=-1/8
-y3次方
=-[(-1/2)3次方]
=-(-1/8)
=1/8

(-y)3次=1/2x1/2x1/2=1/8
-(-y)3次=-(1/2x1/2x1/2)=-1/8
-y3次=-[(-1/2)x(-1/2)x(-1/2)]=1/8
-(-y)3次=-(1/2x1/2x1/2)=-1/8
-y3次=-[(-1/2)x(-1/2)x(-1/2)]=1/8
