最佳解答:

Q: How to simplify the following question? [(a)(a).......(a)]/(a+a+.......+a) ＝ ? Note: [(a)(a)......(a)] means a times and (a+a+......+a) means a terms. Sol: [(a)(a)......(a)]/(a+a+......+a) ＝ aa/[(a)(a)] ＝ aa/a2 ＝ a(a-2) Ans: a(a-2)

其他解答:

[(a)(a)...(a)] / (a+a+...+a) = a^n/na=(a^(n-1))/n
