Which of the following is equivalent to log 8 35 rounded to three decimal places
do I need a calculator for this
Do you mean \(\log_8 35?\)
Yes. You do need a calculator, but you also need to do something else before you do. Most calculators are programmed to use only base 10 and base e. THerefore, you need to use the change of base formula to plug it into a calculator. \[\log_by = \frac{\log_cy}{\log_cb}\]Knowing this, what would \[\log_8 35\]be?
does it have to be a graphing calculator because I cant find that on mine
Only has to be a scientific calculator.
I have a TI-15 and cannot find the log button
Alright. I am unfamiliar with that, so I'm just going to redirect you to wolfram...just make sure that you understand the change of base formula because that's ll this wants you to do. http://www.wolframalpha.com/input/?i=log+35%2Flog+8
\[8^{(1.7097610056483221518)}=35.00000000000000000 \]
