Answer 2

The answer is:  " 156 " .
__________________________________________
Given:  f(x) = 4^(2x) - 100 ;  
__________________________________________
When "x = 2" ; 

f(2) =4^(2*2)  - 100 = [4^(4) ]  - 100 ;
 
        =  (4* 4 * 4 * 4) - 100 ;
       
        =  (16 * 4 * 4) - 100 ;
 
        =  (64 * 4)  - 100 ;

        =  (256) - 100 ; 

        =  156 .
