Question

Answer 1

2) \(A=2016.2018=\left(2017-1\right)\left(2017+1\right)=2017^2-1^2=2017^2-1< 2017^2\)

4) \(A=\left(4^2-1\right)\left(4^2+1\right)\left(4^4+1\right)...\left(4^{2048}+1\right)\)

\(=\left(4^4-1\right)\left(4^4+1\right)...\left(4^{2048}+1\right)\)

\(=\left(4^{2048}-1\right)\left(4^{2048}\right)\)

\(=4^{4096}-4^{2048}< 4^{4096}-1=B\)
