Step-by-step explanation:
 
        
             
        
        
        
(3.5x1016) = 3556
and 
(2.2x1010) = 2222
As per question;
(3556)x(2222) = 10 a*b
By dividing both sides by "10"
we get
(3556)x(222.2) = a*b
or 
(355.6)x(2222) = a*b
by comparing both sides of the equation, 
we get that a = 3556  and b = 222.2
or 
a = 355.6 and b = 2222
        
                    
             
        
        
        
The solution is 4x+2x=6x then 6x+10=solution
