The answer is 5,040

Dark dream is not correct I only got 50%

the answer to 10p4 is 5,040

We know that:

10P4 = 10! / (10 - 4)!

= 10! / 6!

= (10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (6 × 5 × 4 × 3 × 2 × 1)

= 10 × 9 × 8 × 7

= 5,040

Therefore, the answer is 5,040.

Sure, we know that:

10P4 = 10! / (10 - 4)!

= 10! / 6!

= (10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (6 × 5 × 4 × 3 × 2 × 1)

= 10 × 9 × 8 × 7

= 5,040

Therefore, the answer is 5,040.

I need answer

@Reiny could you explain to me how to solve the equation? What does the "C" mean?

Bot can you simplify 10p4

Bot can you please simplify 9c4

We know that:

9C4 = 9! / (4! × (9 - 4)!)

= 9! / (4! × 5!)

= (9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / [(4 × 3 × 2 × 1) × (5 × 4 × 3 × 2 × 1)]

= (9 × 2 × 3 × 7)

= 378

Therefore, the answer is 378.
