okay.........lets generalise........
1.1! +2.2!+3.3!+4.4!+....................+n.n!
n.n! = [n+1-1].n ! = [n+1] ! - n !
Now apply the formula, u will get,
1.1! +2.2!+3.3!+4.4!+....................+34.34!
= [2! - 1! ] + [ 3! - 2! ] +..........................[35!-34!]
= 35 ! - 1!...... all others get cancelled. see again
So..........................I am right..............pls .rate me................bye......
