Evaluate 3! + 4! . 1)30 2)144 3)5,040

Your answer is 1) 30.

This is because the symbol '!' when added on the end of a number stands for "factorial", which means you must multiply together each integer that comes before the given number, and the number itself.

This makes
3! = 3 × 2 × 1 = 6
4! = 4 × 3 × 2 × 1 = 4 × 6 = 24

Then we add together 6 and 24 which gives us 30.

I hope this helps!

If you make it a little more clear i can answer it
