Best ResponseYou've already chosen the best response.3\( 5ln(x2) = 30 \) \(ln(x2) = 6\) \(log_e(x2) = 6\) \((x2) = e^{6}\) Are you able to do it now?

Best ResponseYou've already chosen the best response.0im stuck at the (x2)=e^6

Best ResponseYou've already chosen the best response.3bring the \(2\) to the RHS

Best ResponseYou've already chosen the best response.0i know the answer is e^6 +2 but i dont know where the =2 comes from

Best ResponseYou've already chosen the best response.3Because when you bring the \(2\) to the RHS it's a positive

Best ResponseYou've already chosen the best response.0alright can you walk me through the part after ln(x2)=6

Best ResponseYou've already chosen the best response.3Well you know that \(ln\) can also be written as \(log_e\) right?

Best ResponseYou've already chosen the best response.0so you get e^6= (x2) right

Best ResponseYou've already chosen the best response.3yes; you dont really bring it was called something else which forgot. just simply drag it to RHS. But there is a better name for it lol

Best ResponseYou've already chosen the best response.3\[ e^x  3 =16\] What have you tried?

Best ResponseYou've already chosen the best response.3Um, that is not right..

Best ResponseYou've already chosen the best response.0but its an exponent x3 is the exp. for e

Best ResponseYou've already chosen the best response.0the answer is ln(16)+3

Best ResponseYou've already chosen the best response.3well there is a low chance that wolfram alpha is wrong

Best ResponseYou've already chosen the best response.0oh, well, it looks like we have a paranthesis confusion here. when writing e^x3 = 16, it's important that you write the parantheses aroudnthe (x3), else we can't know that the whole thing is the exponant. So we have this right? \[e ^{x3} = 16\]
