Answer = 90.
Explanation:
First let’s see the values of the given factorials;
3! = 3 x 2 x 1 = 6
4! = 4 x 3! = 24 &
5! = 5 x 4! = 5 x 24 = 120.
Let’s look at the given equation now;
5! – 4! – 4! / 4 = ??
Solving the above equation we get;
= 120 – 24 – (4 x 3!/4)
= 120 – 24 – 6
= 120 – 30
= 90 = Answer
