Factorial 10 to the power factorial 10 will have 7257600 zeros.
242 zeros.
There are 18 zeros.
122 zeros.
There are 24 trailing zeros in 100 factorial.
18 factorial is equal to 6402373705728000 - with three consecutive zeroes at the end.
My calculation gave me 2963 hopefully that is right... * * * * * I suggest 501.
(0!+0!+0!+0!+0!)!=120 !=factorial
if you counted one digit for every particle in the universe it would take over a googol universes.
Two: addition and factorial - the latter being repeat multiplication.
yes. (0!+0!+0!+0!+0!)! where ! refers the factorial of the number
yes. (0!+0!+0!+0!+0!)! where ! refers the factorial of the number
