First, let's simplify the expression:
18! - 1717! - 1616!= 17!(18 - 17 - 16)= 17!(18 - 33)= 17!(-15)
Next, let's simplify the denominator:
17! - 16!= 16!(17 - 1)= 16! * 16
Now, let's divide the two simplified expressions:
(17!(-15)) / (16! * 16)= -15/16
First, let's simplify the expression:
18! - 1717! - 1616!
= 17!(18 - 17 - 16)
= 17!(18 - 33)
= 17!(-15)
Next, let's simplify the denominator:
17! - 16!
= 16!(17 - 1)
= 16! * 16
Now, let's divide the two simplified expressions:
(17!(-15)) / (16! * 16)
= -15/16
