(1/2+1)*(1/3+1)*(1/4+1)*(1/5+1)*……*(1/100+1)
=(3/2)*(4/3)*(5/4)*(6/5)*……*(101/100)
=101/2

3/2 * 4/3 * …… 100/99 *101/100 =101/2 = 50.5

(1/2+1)*(1/3+1)*(1/4+1)*(1/5+1)*……*(1/100+1)
=(3/2)(4/3)(5/4)(6/5)……(100/99)(101/100)
=(1/2)(3/3)(4/4)(5/5)……(100/100)*101
=101/2

3/2*4/3*5/4*6/5........*101/100=101/2

原式=3/2*4/3*5/4*...*101/100=101/2

上式=3/2*4/3*5/4......101/100=101/2=50.5
