Best ResponseYou've already chosen the best response.1Yes. 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?
