Math Problem Statement
P(7, 4) · P(6, 3)
P(5, 4)
Solution
The expression you've provided involves permutations. The permutation formula is defined as:
where:
- is the total number of items.
- is the number of items to be chosen.
Let's break down each part of the expression:
1.
2.
3.
Now, combine them as per the given expression:
So, the final value of the expression is 840.
