 lim_(x→∞)  ((4^x (4^(−2) +((3/4))^x +((1/2))^x ))/(4^x (4^(−1) +3((3/4))^x )))  = lim_(x→∞) (((4^(−2) +((3/4))^x +((1/2))^x )/(4^(−1) +3((3/4))^x )))   = (4^(−2) /4^(−1) ) = 4^(−1) .

lim_(x→∞) ((4^(x−2) +3^x +2^x )/(4^(x−1) +3^(x+1) ))  =(((1/4^2 )+((3/4))^x +((2/4))^x )/((1/4)+3((3/4))^x ))=(((1/4^2 )+0+0)/((1/4)+3(0) )) =(1/4)
