Answer:

1. 4P2 or P(4,2)

= n!/(n-r)!

= 4!/(4-2)!

= 4•3•2•1/2!

= 24/2

= 12

2. 6P2 or P(6,2)

= n!/(n-r)!

= 6!/(6-2)!

= 720/4!

= 720/24

= 30

3. 6P6 or P(6,6)

= n!/(n-r)!

= 6!/(6-6)!

= 720

4. -4+7P4 or P(7,4)

= -4 + 7!/(7-4)!

= -4 + 5040/3!

= -4 + 5040/6

= -4 + 840

= 836

5. 5•6P5 or 5•P(6,5)

= -5 • 6!/(6-5)!

= -5 • 720/1!

= -5 • 720

= 3600
