✔ 最佳答案
a,a^2,a^3,a^4,...,a^100的積=a^(1+2+3+ ... + 99+100)
=a^[(1+100)*(100/2)]
=a^(101*50)
=a^5050

求a,a^2,a^3,a^4,...,a^100的積
= a^(1+2+3+4......+99+100)
= a^[(1+100)x100]/2
= a^(10100/2)
= a^5050
2008-09-27 15:02:21 補充：
= a^{[(1+100)x100]/2}
= a^(1+2+3+4......+99+100)
= a^[(1+100)x100]/2
= a^(10100/2)
= a^5050
2008-09-27 15:02:21 補充：
= a^{[(1+100)x100]/2}
