I asked Mathematica, and it gave the list
3, 7, 11, 19, 23, 31, 43, 47, 59, 67, 71, 79, 83
which contains 13 primes.
Hi,
How many primes are there of the form less than ?
Im thinking the answer is 13, but possible it might be 12? depending on whether x=0, prime=3 counts? or maybe neither are right!
help appreciated!
Thanks :-)
