Answer:
a
Step-by-step explanation:
The ! mean factorial, so 4! would be 4 factorial and 3! would be 3 factorial. Remember, n! is:
1 × 2 ... × n
where n is an integer. Using this, we can find 4! and 3!.
4! would be:
1 × 2 × 3 × 4 = 24
So 4! would be 24.
3! would be:
1 × 2 × 3 = 6
So 3! would be six.
We are trying to find 4! + 3!. To do this, plug in 24 for 4! and 6 for 3!:
4! + 3! = 24 + 6 = 30
So 4! + 3! = 30.
The answer is a.
I hope this helps. :)
