Hello,
Can someone tell me how to type log10 on a TI83plus.fr?
I was given an answer to calculate the decrease in sound pressure level
from a speaker with the increase in distance (20 * log10 of the distance) but I don't know how to do the calculation on my TI.
Thank you in advance for your help.

'Howdy, logarithms have several names on calculators, including your TI-83:
- the natural logarithm (base e), named ln
- the logarithm base 10, named log10 or simply log, that's what you're looking for (its key is above ln)
- logarithms of other bases can be calculated using the formulaln(number)/ln(base)
