Write in Exponential Form y = natural log of x
y
=
ln
(
x
)
y
=
ln
(
x
)
Step 1
For logarithmic
equations
,
log
b
(
x
)
=
y
log
b
(
x
)
=
y
is
equivalent
to
b
y
=
x
b
y
=
x
such that
x
>
0
x
>
0
,
b
>
0
b
>
0
, and
b
≠
1
b
≠
1
. In this case,
b
=
e
b
=
e
,
x
=
x
x
=
x
, and
y
=
y
y
=
y
.
b
=
e
b
=
e
x
=
x
x
=
x
y
=
y
y
=
y
Step 2
Substitute the values of
b
b
,
x
x
, and
y
y
into the
equation
b
y
=
x
b
y
=
x
.
e
y
=
x
e
y
=
x
y
=
