Answer:

[tex]P(9,3) *P(5,4)[/tex]

And if we use the permutation formula given by:

[tex] nPx = \frac{n!}{(n-x)!}[/tex]

And replacing we got:

[tex] \frac{9!}{6!} \frac{5!}{4!}= 504*5 = 2520[/tex]

Step-by-step explanation:

For this problem we want to find the following expressionÑ

[tex]P(9,3) *P(5,4)[/tex]

And if we use the permutation formula given by:

[tex] nPx = \frac{n!}{(n-x)!}[/tex]

And replacing we got:

[tex] \frac{9!}{6!} \frac{5!}{4!}= 504*5 = 2520[/tex]
