tkxb Posted September 23, 2010 Report Share Posted September 23, 2010 So I don't understand the last part of a type 1 Math SL IA. It says:Let logaX=c and logbX=d. Find the general statement that expresses logabX, in terms of c and d (a and b in the logs are both supposed to be subscript).Any help would be greatly appreciated!Use a change of base formula. My teacher gave us a hint, LogabX = logX/Logab = logX/loga+logbAssumptions: ac = bd = xI don't know how to elaborate more without violating the answer rule thing, but yea. Hope this helps.

love_TFT Posted December 14, 2010 Report Share Posted December 14, 2010 My IA is due tomorrow and i'm stuck on this portion of the IA where it asks to find the general statement that expresses logabX in terms of c and d. How should i go about finding and explaining how to do this? Reply Link to post Share on other sites More sharing options...
unknown88 Posted January 17, 2011 Report Share Posted January 17, 2011 i have found the general statement in terms of logarithms and exponential terms but not in terms of p/q, help anybody? Reply Link to post Share on other sites More sharing options...

Mahuta ♥ Posted January 19, 2011 Report Share Posted January 19, 2011 Expressing it in terms of p/q is the expression you get after you calculate all the logarithms and put them in terms of p/q.Try doing that for each sequence, you will find the same p/q for each.

eli:):) Posted September 19, 2011 Report Share Posted September 19, 2011 Convert it into base 10, you want those technology marks. I think I did some of them using the natural base to make it look fancier . please can you tell me how to do that , i'm lost in math , i hope you're online Reply Link to post Share on other sites More sharing options...
ripziro Posted January 16, 2012 Report Share Posted January 16, 2012 I'm doing this portfolio right now. I just have one question. What is the most effective way to justify the expressions using technology? (Also I assume that everyone got k/n as the expression for the general sequence) Reply Link to post Share on other sites More sharing options...
