Best ResponseYou've already chosen the best response.0it won't let me type the neg so i don't think it is neg

Best ResponseYou've already chosen the best response.0I'm confused on how to set it up

Best ResponseYou've already chosen the best response.3try practicing a few similar problems

Best ResponseYou've already chosen the best response.3like ; transform to exponent form log10 100 = 2 answer 10^2 = 100

Best ResponseYou've already chosen the best response.0i think I'm just overthinking this

Best ResponseYou've already chosen the best response.3maybe remember that the log is the exponent and the base is the value that the goes 'under' the exponent

Best ResponseYou've already chosen the best response.3yea with practice you will if a get confused i write the log10 reelation then compare it with the one in the problem log10 100 = 2 wand know that 100 = 10^2

Best ResponseYou've already chosen the best response.0okay yeah i get that part

Best ResponseYou've already chosen the best response.3so if we have ln(x + 1) = 1 e relates to 10 , x + 1 relates to 100 and 1 relates to 2

Best ResponseYou've already chosen the best response.3remember that ln = log to the base e

Best ResponseYou've already chosen the best response.0but idk where your getting the e at

Best ResponseYou've already chosen the best response.0that is right to the hundredths place ln is the same as log_e so the equation you had could have been written as: \[1=\log_e(x+4) \\ e^1=x+4 \text{ is the same equation in exponential form } \\ e=x+4 \\ \] and yes subtracting 4 on both sides gives you x is approximately 1.28

Best ResponseYou've already chosen the best response.0the equation you typed was 1=ln(x+4) which does imply to the 100ths x=1.28

Best ResponseYou've already chosen the best response.3are you sure your question is correct?

Best ResponseYou've already chosen the best response.0or the equation he typed is not the equation he should have typed

Best ResponseYou've already chosen the best response.0or... there is one other or but very unlikely the meaning of ln in most subjects mean log base e maybe ln means log base 2 because he is in computer science :p

Best ResponseYou've already chosen the best response.3oh  i've never seen ln defined that way..

Best ResponseYou've already chosen the best response.0i copied and pasted and we even used the right formula and everything

Best ResponseYou've already chosen the best response.0sometimes copy and paste doesn't work out so smoothly because you copying and pasting from a format that doesn't always translate over smoothly

Best ResponseYou've already chosen the best response.0the equation looks exactly like 1=ln(x+4) ?
