Question

Solve for x.

lnx - ln(x +1) = 1

Answer 1

lnx(1/x+1)=1

Answer 2

LN properties subtraction is really division

Answer 3

ln (x/x+1) = 1
x/x+1 = e^1
x=e^1 +xe^1
x-xe^1 = e^1
x(1-e^1)=e^1
x=[e^1/(1-e^1)]

Answer 4

apparently though, e/1-e is extraneous so its no solution, i don't understand that...

Answer 5

to remove a ln you must raise to the power of e

Answer 6

you cannot take the ln of a number less then 0

Answer 7

i don't see how that applies to this though..
