Answer 1

f(x)=156

Explanation:

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 .
