Best ResponseYou've already chosen the best response.1It says \[\Large 5^y = 12\] right?

Best ResponseYou've already chosen the best response.1what undoes exponents?

jim_thompson5910

Best ResponseYou've already chosen the best response.1if we solve for y, we get \[\Large 5^y = 12\] \[\Large y = \log_{5}(12)\] \[\Large y = \frac{\log(12)}{\log(5)}\] \[\Large y \approx 1.543959\]

jim_thompson5910

Best ResponseYou've already chosen the best response.1So find the function where if you plug in x = 12, you'll get roughly y = 1.543959

Best ResponseYou've already chosen the best response.0wait so if i graphed them would the answer show up as one of theoptions?

jim_thompson5910

Best ResponseYou've already chosen the best response.1look at your options which choice has (12, 1.543959) on it?

jim_thompson5910

Best ResponseYou've already chosen the best response.1obviously B and C are out because the y coordinates of the point with x coordinate 12 is negative
