Math Problem Statement

Simplify the expression: P_5 - 3! + 0! + P_2 - P(2,3) + P(10,4)

Solution

The equation in the image is:

P53!+0!+P2P(2,3)+P(10,4)P_5 - 3! + 0! + P_2 - P(2,3) + P(10,4)

Let's break it down:

  1. P5P_5: Likely refers to the permutation of 5 objects, P(5,5)P(5,5), which equals 5!5!.
  2. 3!3!: Factorial of 3, which equals 66.
  3. 0!0!: Factorial of 0, which equals 11.
  4. P2P_2: Likely refers to P(2,2)=2!P(2,2) = 2!.
  5. P(2,3)P(2,3): This seems incorrect because you cannot have 3 objects chosen from 2. I will assume it's an error.
  6. P(10,4)P(10,4): This is the number of ways to arrange 4 objects from 10, given by 10!(104)!=10!6!\frac{10!}{(10-4)!} = \frac{10!}{6!}.

Solving:

  • P5=5!=120P_5 = 5! = 120
  • 3!=63! = 6
  • 0!=10! = 1
  • P2=2!=2P_2 = 2! = 2
  • P(2,3)P(2,3) is invalid, but I'll treat it as 0 or possibly ignored.
  • P(10,4)=10!6!=10×9×8×71=5040P(10,4) = \frac{10!}{6!} = \frac{10 \times 9 \times 8 \times 7}{1} = 5040

Now substitute into the equation:

1206+1+20+5040=5157120 - 6 + 1 + 2 - 0 + 5040 = 5157

So, the result is:

51575157
