Question

how to find x for ln(3-x)=1 ??

Answer 1

is it ln(3)-ln(x)=ln(1)
0-ln(x)=0
ln(x)=0

Answer 2

no its not

Answer 3

so how to do it @rizwan_uet

Answer 4

should i take the base e to remove "ln "

Answer 5

3-x=e^1
x=e^1-3
x=-0.281718
@rizwan_uet

Answer 6

ln(3-x) = 1 = ln e

ln3 - lnx = ln e

ln(3/x) = ln e

3/x = e

now you can find x

Answer 7

x=3/e
x=1.1036
if i substitute x inside ln(3-1.1036) not = to 1 @rizwan_uet

Answer 8

x=0.6399

Answer 9

\( \ln(3-x)=1 \)

\( 3-x=e^1 \)

\( x=3-e \)

Answer 10

Thanks @ganeshie8

Answer 11

np :) e is just a number, plug the value of e if u want.

Answer 12

yeah now i know that e=2.7182 @ganeshie8

Answer 13

good :)
