The image contains a mathematical problem asking to compute several factorial expressions. Let me solve each part for you.

### Problem Breakdown
The problem asks to compute the values for the following expressions:

**a.** \(3!\)  
**b.** \(4! - 2!\)  
**c.** \(6! \times 2\)  
**d.** \(\frac{8!}{5! \times (8-5)!}\)  
**e.** \(\frac{10!}{9!} \times 2!\)  

Let's calculate each part one by one.

### Solutions:

**a.** \(3! = 3 \times 2 \times 1 = 6\)

**b.**  
\(4! = 4 \times 3 \times 2 \times 1 = 24\)  
\(2! = 2 \times 1 = 2\)  
So, \(4! - 2! = 24 - 2 = 22\)

**c.**  
\(6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 720\)  
\(6! \times 2 = 720 \times 2 = 1440\)

**d.**  
The expression can be simplified as:  
\[
\frac{8!}{5! \times (8-5)!} = \frac{8!}{5! \times 3!}
\]  
Now, compute the factorials:  
\(8! = 8 \times 7 \times 6 \times 5!\)  
\(5! = 5 \times 4 \times 3 \times 2 \times 1 = 120\)  
\(3! = 3 \times 2 \times 1 = 6\)

So:  
\[
\frac{8!}{5! \times 3!} = \frac{8 \times 7 \times 6 \times 5!}{5! \times 6} = \frac{8 \times 7}{1} = 56
\]

**e.**  
\[
\frac{10!}{9!} \times 2! = (10 \times 9!) / 9! \times 2! = 10 \times 2! 
\]  
Since \(2! = 2\),  
\[
10 \times 2 = 20
\]

### Final Answers:
- **a.** 6  
- **b.** 22  
- **c.** 1440  
- **d.** 56  
- **e.** 20
