Question about Texas Instruments TI-86 Calculator
Your calculator cannot compute directly the logarithms in an arbitrary base, but you have the means to obtain that indirectly.
You can use either of the conversion formulas shown on the screen capture (on the right). On screen capture ln stands for natural logarithm.
If you want binary logarithms (logs in base 2) you use the relation
log_2 (x) =ln(x)/ln(2)
Use whichever formula is shorter to key in (without pressing the 2nd key).
Hope it helps.
