Calculating Factorials
Let's break it down step by step:
Finding 5!
5! (5 factorial) is calculated as:
- 5! = 5 × 4 × 3 × 2 × 1 = 120
Finding 4!
Next, we calculate 4! (4 factorial):
- 4! = 4 × 3 × 2 × 1 = 24
Combining the Results
Now, we can multiply the two results together:
- 5! × 4! = 120 × 24
Final Calculation
Now, let's do the multiplication:
- 120 × 24 = 2880
Final Answer
Thus, the value of 5!4! is 2880.
