how much is two to the power three to the power three?
134217728, I think, I'm not 100% sure but that is what i think
2^3^3 = 512
(two to the power of three) to the power of three = 512
two to the power of (three to the power of three) = 134,217,728
these confuse me a little but by convention you mean
\(2^{(3^3)}=2^{27}\)
