Best ResponseYou've already chosen the best response.1Whenever you have a log problem and the base isn't written, it's a given that it's 10. So the question would look like \[\log _{10}0.0001\] which can be rewritten \[10^{x} = 0.0001\] Now you have to find a common base of 10 and 0.0001. Basically, 10 to what power equals 0.0001?

Best ResponseYou've already chosen the best response.1Well, with an answer less than 1, know that it's going to be a negative power. Ex. \[10^{1} = 0.1\]Now count the number of of decimal places to the right that 0.0001 goes to, which is four. So \[10^{4} = 0.0001\]Try in on your calculator and see. There is a better way to figure it out, but that's how I do it.

Best ResponseYou've already chosen the best response.0Oh I see that! I was thinking maybe it would be a negative but wasnt sure. So this equation simplified is \[10^4 ?\]
