=s^142006-10-30 14:26:49 補充：
因為:1. 任何數 (除0之外) 的 0 次方係 = 12. 如果想將分子掉上去分母度, 就要將佢0既指數乘 (-1) 3. (a^n)^m = a^(n x m) = a^nm所以:. -r^0(--------) ^2. .s^-7. . .1=(------) ^2, (because of rule 1). . s^-7= (s^ (-7 x -1))^2, (because of rule 2)= (s^7)^2= s^(7x2), (because of of 3)= s^14

1. (-r^0/s^-7)^2
= (-1/s^-7)^2
= [-1/(1/s^7)]^2
= -(-s^7)^2
= s^14
= (-1/s^-7)^2
= [-1/(1/s^7)]^2
= -(-s^7)^2
= s^14

(-r^0/s^-7)^2
=(s^7)^2
=s^14
=(s^7)^2
=s^14

(-r^0/s^-7)^2
=(-1/s^-7)^2 any number power to 0 =1, e.g r^0=1
=(s^7)^2
=s^14

insert into layer 3(-s^7)^2
=(-1/s^-7)^2 any number power to 0 =1, e.g r^0=1
=(s^7)^2
=s^14
