看到大家积极的发JJ，自己心里“着急”啊！不过还是先请教一道题吧GWD-4-22

4-22, For any integer k greater than 1, the symbol k* denotes the product of all the fractions of the form 1/t, where t is an integer between 1 and k, inclusive. what is the value of 5*/4*?

what does " the product of all the fractions of the form 1/t" mean? this is the critical part of question.....

anybody can help to solve this question?

it means k*=(1/1)*(1/2)*(1/3)*...*(1/k)

so 5*=1/1 * 1/2 * 1/3 * 1/4 * 1/5

4* = 1/1 * 1/2 *1/3 * 1/4

so 5*/4* = 1/5
