Tower Of Twos

Let \(T(n)\) be the tower of powers of \(2\) of height \(n\). For example:

  • \(T(3) = 2^{2^2} = 2^4 = 16\)

  • \(T(4) = 2^{2^{2^2}} = 2^{16} = 65536\)

So the last digit of \(T(4)\) is \(6\).

Part A Determine the last two digits of \(T(100)\).
Part B Determine the remainder when \(T(2021)\) is divided by \(2021\).
