Best ResponseYou've already chosen the best response.1Is that \[y = \log_3(x)\]? use the log identity \[y = \log_b(x)\qquad\iff\qquad b^y=x \]

Best ResponseYou've already chosen the best response.0Yeah I know that but how is it done with a negative between 3 and logx

Best ResponseYou've already chosen the best response.1oh it is a negative? like this \[y = 3\log(x)\]?

Best ResponseYou've already chosen the best response.0No its suppose to be a negative between the three and y

Best ResponseYou've already chosen the best response.1oh , right i erred \[y = 3  \log (x)\\ \log(x) = 3y\\ x = 10^{3y}\]

Best ResponseYou've already chosen the best response.1\[y = 3  \log (x)\]add log x to both sides of the equation, \[y+\log(x) = 3\]take away y from both sides .\[\log(x) = 3y\]then applied log identity \[x = 10^{3y}\]
