The answer would be 8x^4 + 16x^3y - 48x^2y^2
In order to find this, multiply 8x^2 by each term individually.
8x^2 * x^2 = 8x^4
8x^2 * 2xy = 16 x^3y
8x^2 * -6y^2 = -48x^2y^2 
Now you can put them all in a row. 
 8x^4 + 16x^3y - 48x^2y^2
 
        
             
        
        
        
Answer:
27,600
Step-by-step explanation:
We use the following formula:-  
Number of permutations of r from n 
 = nPr
= n! / (n-r)!
I am assuming you don't allow repeated letters in the 4 letter codes.
Take S as the first letter. Then we have 3 letters extra out of 25 letters.
Using the above formula the possible ways of doing this is 
25! / (25 - 3)!
25! / 22!
 = 25*24*23
= 13800.
The same number is obtained if the first letter is a T.
 So the answer is 2*13800
= 27,600
