Re: Creative Problem Solving

For the question about number of operations, does the negative sign count as an operation? As you could define the negative sign as subtracting from zero, so you would get 3^9 possibilities...

Also, for "Without doing calculations, determine (and prove) which of 31^11 and 17^14 is greater." question, couldnt you use logarithms?

NOTE: I dont know the symbol for "Is greater, less than, or equal?" so I use ... OK?
31^11 ... 17^14
11ln31 ...14ln17
e^11 + 31 ... e^14 + 17
so, if e^3 > 14, then 17^14 > 31^11
Define e as ~2.7
2.7^3 = 19.683
(But, I dont know as much as you guys seem to know, so I could be wrong...)
