0 unreality Posted July 13, 2007 Author Report Share Posted July 13, 2007 i will give the answer for both, but it only makes sense if you know what you're doing. These answers are more like hints... 1)5x8 = 18 2)x=22 The question is... why? Quote Link to comment Share on other sites More sharing options...
0 unreality Posted July 15, 2007 Author Report Share Posted July 15, 2007 looks like nobody knows so: a) 5x7 = 13 and 5x8 = 18 because its base 32 b) 7=13 and 10=22 because its base 4 Quote Link to comment Share on other sites More sharing options...
