A question from a math noob...

Is there a way to simplify the following? $$2^{2^{n-1}}$$

Thanks in advance!

  • $\begingroup$ In general, exponents in a "tower" like that are hard to simplify. Maybe you could try $$2^{2^{n - 1}} = 2^{2^{n}/2} = \sqrt{2}^{2^{n}}$$ $\endgroup$ – Joshua Wang Feb 1 at 3:23

Not really. $2^{2^{n-1}}$.

If it’s part of an equation you can take the log $2^{n-1} log 2$. Another log and you get $(n-1)log 2 + log log 2$.
