Answer 1

a = (4^2)^4  : 2^6 : 2^6 = (2^2)^8 : 2^6 : 2^6 = 2^16 : 2^6 : 2^6 = 2 ^(16-6-6) =2^4 

b = 5^4 - 2^2 x 11^2 - 11^2 = 5^4 - 11^2 x (2^2 + 1) = 625 - 121 x5 =625 - 605 = 20  

Answer 2

$a = (4^2)^4:2^6:(2^2)^3 = 4^{2\cdot 4}:2^6:2^{2\cdot 3} = 2^{2\cdot 2\cdot 4}:2^6:2^6 = 2^{16} : 2^6:2^6 = \\ =2^{16-6-6}= 2^{16-12} = 2^{4} \Rightarrow \boxed{a = 2^{4}} \\ \\ \\ b = 5^4-(2\cdot11)^2-11^2 = 5^4 - 2^2\cdot11^2-11^2 =5^4-11^2\cdot(2^2+1)= \\ =5^4-11^2\cdot(4+1) = 625 - 121\cdot 5 = 625 - 605 = 20 \Rightarrow \boxed{b = 20}$
