find the value of 1!+2!+.....+50!

• 50!+49!+48!+.....1!
  50![1+(1/50)+(1/49*50)+....]
  50!(1+0.2+0.004+....)[neglect lower values]
  50!*1.02 is the answer

• 3.1035*10^64.....but i don't know the exact solution..
• 11 years agoHelpfull: Yes(4) No(4)
• we have common 50! fro the series.......
  50![1!+49!/50!]=51!/50
• 11 years agoHelpfull: Yes(4) No(0)
• we can write it as..
  50!+49!+48!+.........+1!
  50![1+(1/50)+(1/50*49)+............+(1/50!)]
  50![1+0.2] (neglecting higher order terms)
  50!*1.02
  3.102237507*10^64
  which is equal to 51!/50......ans
  ans=51!/50
• 11 years agoHelpfull: Yes(1) No(2)
• formula:1!+2!+......n!=(n+1)!/n
  so answer is 51!/50
• 11 years agoHelpfull: Yes(1) No(1)
• 50!-1
  
  
  
• 11 years agoHelpfull: Yes(0) No(4)
• formula for n! is=n(n-1)!
  so answer is=50(49!)
• 11 years agoHelpfull: Yes(0) No(4)
• 50!-1 Ans.
