Answer 3

\(3\left(2^2+1\right)\left(2^4+1\right)...\left(2^{64}+1\right)+1\)

\(=\left(2-1\right)\left(2+1\right)\left(2^2+1\right)\left(2^4+1\right)...\left(2^{64}+1\right)+1\) 

\(=\left(2^2-1\right)\left(2^2+1\right)\left(2^4+1\right)...\left(2^{64}+1\right)+1\) 

\(=\left(2^4-1\right)\left(2^4+1\right)...\left(2^{64}+1\right)+1\)

\(.....\)

\(=\left(2^{64}-1\right)\left(2^{64}+1\right)+1\)

\(=\left(2^{128}-1\right)+1\)

\(=2^{128}\)
