0 Guest Posted August 2, 2007 Report Share Posted August 2, 2007 There's hardly any activity out here! C'mon ppl give it a shot, its not that difficult as it looks... Do you know the answer? The 50-50-90 rule: Anytime you have a 50-50 chance of getting something right, there's a 90% probability you'll get it wrong & yes, i was given this problem recently and was given ten min's to figure it out, thankfully it struck in the 1st min... Number of digits # 10 ^ 2953564278 Now, here's the tough / easy part given the answer: Explain the reasoning Quote Link to comment Share on other sites More sharing options...
0 Guest Posted August 2, 2007 Report Share Posted August 2, 2007 It took me a little while, but once I got it I see how someone else could get it much quicker than I did. I would have been pushing the 10 minute time limit. 345893456 * log(345893456) Quote Link to comment Share on other sites More sharing options...

0 unreality Posted August 3, 2007 Report Share Posted August 3, 2007 i dont understand... using Log on the second number changes the equation, doesnt it? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted August 3, 2007 Report Share Posted August 3, 2007 i dont understand... using Log on the second number changes the equation, doesnt it? Of course it does, hence the 10 ^ ____ in the answer! y = x^x (read raised to) log y = x * log x (log to the base 10) Now go back to logarithmic basics and think!
