Recognize the equation:
Recognize the equation
5
=
3
x
5 = 3^x
5
=
3
x
is an
exponential equation
where we need to find the value of
x
x
x
.
Use logarithms:
Since
5
5
5
is not a power of
3
3
3
, we can't find an integer value for
x
x
x
. We'll have to use logarithms.
Take logarithm:
Take the logarithm of both sides of the equation to get
log
(
5
)
=
x
⋅
log
(
3
)
\log(5) = x \cdot \log(3)
lo
g
(
5
)
=
x
⋅
lo
g
(
3
)
.
Divide to isolate
x
x
x
:
Divide both sides by
log
(
3
)
\log(3)
lo
g
(
3
)
to isolate
x
x
x
, so
x
=
log
(
5
)
log
(
3
)
x = \frac{\log(5)}{\log(3)}
x
=
l

.
Calculate with calculator:
Use a calculator to find the values of
log
(

)
\log(5)
lo
g
(
5
)
and
log
(
3
)
\log(3)
lo
g
(
3
)
.
Find
x
x
x
value:
Calculate
x
=
log
(
5
)
log
(
3
)
x = \frac{\log(5)}{\log(3)}
x
=
l
o
g
(
