Answer:

$\huge \boxed{90}$

Explanation:

First thing you do is subtract.

10-2=8

$\displaystyle (10!)/(8!)$

Then you cancel the factorials.

$\displaystyle (10!)/(8)=10*9$

Multiply numbers from left to right to find the answer.

$\displaystyle 10*9=90$

$\huge \textnormal{90}$ , which is our answer.

Hope this helps!
