n! n! For the given values of n and r, evaluate (a) (n - r)! and (b) r!(n - r)! for n = 10 and r = 4. n! (a) When n = 10 and r = 4, (n - r)! (Simplify your answer. Type an integer or a simplified fraction.) n! (b) When n = 10 and r = 4, r!(n - r)! (Simplify your answer. Type an integer or a simplified fraction.)Write (in the same base) the counting numbers just before and just after the given number. (Do not convert to base ten.) 46 seven The base-seven counting number just before 465even is Dseven. The base-seven counting number just after 46seven Is seven.
