Re: Math Quiz
If anybody's still interested here's the solution:
The number of proper subsets of a set containing N elements is 2N -1.
For N=30000, the number of proper subsets is 230000 -1.
The "-1" totally insignificant for such a large N.
Find "x" such that 10x = 230000...
take log10 of both sides:
log10(10x) = log10(230000) ..∴.. x = 30000*log10(2) = 9030.9
109030.9 = 100.9 * 109030 = 7.94E9030
