It is 9 because you have a 30,60,90 triangle, and then you can use pythagorean theorem.
        
                    
             
        
        
        
 The answer is:  10 x¹³ y¹⁰  . 
__________________________________________________________
1x^8 *  2y^(10) * 5x^5 = 
1* 2* 5 * x^8 * x^5 * y^(10) = 
10 * x^(8+5) * y^(10) =
10 * x^(13) * y^(10) = 10 x^(13) y^10 ;  write as:
