- Is there an irrational number t such that 2^t and 3^t are
- both rational? Is this question still open? The answer is
- yes if we just consider 2^t (2^{log_2 3} being an example)
- but no if we look at 2^t, 3^t and 5^t.(This is a case
- of the famous "6 exponentials theorem.") The general case
- of a^t and b^t, a and b integers, is still open.
