(1/50-1)(1/49-1)(1/48-1).(1/4-1)(1/3-1)(1/2-1)
计算(50/1-1)(49/1-1)(48/1-1).(4/1-1)(3/1-1)(2/1-1)
1/1×1/2×1/3+1/2×1/3×1/4+1/3×1/4×1/5+...+1/48×1/49×1/50
(1/50)(1/49)(1/48).(1/4)(1/3)(1/2)这个数学题怎么做?
计算(50/1)(49/1)(48/1)…(4/1)(3/1)(2/1)的值
计算:(1/50-1)×(1/49-1)×(1/48-1)×…×(1/4-1)×(1/3-1)
(1-1/50)(1-1/49)(1-1/48)…(1-1/4)(1-1/3 省略啦乘号!
(1-1/50)×(1-1/49)×(1-1/48)×…×(1-1/4)×(1-1/3)
计算. (1/50-1)×(1/49-1)×(1/48-1)×```×(1/3-1)×(1/2-1)
计算 (50/1-1)(49/1-1)(48/1-1)...(4/1-1)(3/1-1)(2/1-1)
计算 (50/1-1)(49/1-1)(48/1-1)...(4/1-1) (3/1-1)(2/1-1)
(1/50-1)(1/49-1)(1/48-1)…(1/4-1)(1/3-1)(1/2-1)[等于多
计算(1-1/50)(1-1/49)(1-1/48).(1-1/4)(1-1/3)(1-1/2)=?
