Best ResponseYou've already chosen the best response.0hey sorry afk again. this is what I did (30000=1.18^x * 15 30000=1.18^x * 500) I used scalar multiplying

Best ResponseYou've already chosen the best response.0my book has a whole section on that in this lesson so I thought that was what I do but idk

Best ResponseYou've already chosen the best response.1i don't know why or how you separated de 15 and 5000\[\huge\rm 30000=15500(1.18)^x\] you need to get rid of the 15500 so you can take ln both sides

Best ResponseYou've already chosen the best response.1divide both sides by 15500 and then take natural log

Best ResponseYou've already chosen the best response.0okay so 30000 / 15500 is 1.9354 and then just 1.18^x I think

Best ResponseYou've already chosen the best response.1yes right \[\huge\rm 1.935=(1.18)^x\] now take natural log both sides

Best ResponseYou've already chosen the best response.0isn't natural log just log10? I think someone told me that

Best ResponseYou've already chosen the best response.1ln is basically same as log same rules applies for both but ln has base e and and log_!0

Best ResponseYou've already chosen the best response.1sure btw you can take ln or log you will get the same answer if you take `ln` \[\huge\rm \color{ReD}{ln} 1.935=\color{red}{ln}(1.18)^x\] or `log` \[\huge\rm \color{ReD}{log} 1.935=\color{red}{log }(1.18)^x\]

Best ResponseYou've already chosen the best response.1now apply the power rule \[\large\rm log_b x^y = y \log_b x\]
