Evaluate The Factorial Expression (n + 4)!/(n + 4)
Evaluating (n + 4)! / (n + 4) gives (n + 3)!.
Evaluating Factorial Expressions
To evaluate a basic factorial expression, n!, we multiply n × (n – 1) × (n – 2) × . . . × 3 × 2 × 1. That is, we multiply all of the integers from n down to 1 together. Using this definition of factorials, we can evaluate more involved factorial expressions.
