✔ 最佳答案
(-c^2)^3=-c^(2*3)
=-c^6
(-c^2)^4
= (c^2)^4
= c^(2*4)
= c^8

(-C^2)^3
= -(C^2)^3
= -(C)^2x3
= -C^6
(-c^2)^4
=-(c)^2x4
=-(c)^8
2008-05-12 10:15:58 補充：
(-x^a)^n=-(x)^an
= -(C^2)^3
= -(C)^2x3
= -C^6
(-c^2)^4
=-(c)^2x4
=-(c)^8

(-C^2)^3
= -(C^2)^3
= -(C)^2x3
= -C^6

(-C)^2 同 (-C^2) 係唔同嫁wor
= -(C^2)^3
= -(C)^2x3
= -C^6
