The given expression can be simplified as follows:
n−10n-10n−10! / 3! n−3n-3n−3!
= n−10n-10n−10! / 3! * n−3n-3n−3n−4n-4n−4n−5n-5n−5...222111
= n−10n-10n−10n−9n-9n−9n−8n-8n−8...333222111 / 333222111
= n−10n-10n−10n−9n-9n−9n−8n-8n−8...333
Therefore, the simplified expression is n−10n-10n−10n−9n-9n−9n−8n-8n−8...333.
