 +  =
 =  Since, we have the same common denominator
   Since, we have the same common denominator
now divide 
14÷4 =3.5 = 3 
 
Therefore, there are 3 of 3/4 with a remainder of   in 3
 in 3  .

Answer:
156
Step-by-step explanation:
f(x)= 4^(2x) -100
Let x =2
f(2)= 4^(2*2) -100
    = 4^4 - 100
    = 256 -100
    = 156
