Answer:

[tex]\huge \boxed{90}[/tex]

Step-by-step explanation:

First thing you do is subtract.

10-2=8

[tex]\displaystyle \frac{10!}{8!}[/tex]

Then you cancel the factorials.

[tex]\displaystyle \frac{10!}{8}=10\times9[/tex]

Multiply numbers from left to right to find the answer.

[tex]\displaystyle 10\times9=90[/tex]

[tex]\huge \textnormal{90}[/tex], which is our answer.

Hope this helps!
