BHASKAR MANDAL  (9 years ago)

1!+2!+3!+4!+...+50!
= 50! (1!/50! + 2!/50! + .........49!/50! + 50!/50! )
= 50! (1!/50! + 2!/50! + .........1/50 + 1 )
in the bracket only 1/50 and 1 have values other will be negligible,
so approximately we can write
= 50! (51/50 )
= 1.02*50
= 1.02 * 3.04 * 10^64
= 3.1008 * 10^64
