Question

With a nod to try this:

Let there be an infinite sequence of exponentiation t = xx...

I don't know whether that could be expressed with up arrows or not, but Rainman's arrows reminded me of this.

Anyway, there is an infinite sequence of higher and higher order exponents in this expression.

Show that if t = 2 then also t = 4.
