Evaluate.
4! + 3!
a. 30
b. 720
c. 5,040

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.
