Hi
I have just been given an exponent to test for GIMPS - it is 34642837. How do I work out how many digits it has please? I've looked at some of Mersenne primes listed and divided the exponent by the number of digits and always seem to get around 3.32192807. Dividing my expoent by this gives, to the nearest whole number, 10428533 (or, dividing some other exponents by numbers of digits, 10428534 or 10428535). Does this mean 2^{34642837} has 10428533 digits please?
Thanks
