Q.
What is the value of
ln
e
2
3
\ln \sqrt[3]{e^{2}}
ln
3
e
2
?
Rewrite cube root of
e
2
e^2
e
2
:
We are given the expression
ln
(
e
2
3
)
\ln(\sqrt[3]{e^{2}})
ln
(
3
e
2
)
. The
3
\sqrt[3]{}
3
indicates a cube root. We can rewrite the cube root of
e
2
e^2
e
2
as
(
e
2
)
1
3
(e^2)^{\frac{1}{3}}
(
e
2
)
3
1
.
Simplify using logarithm property:
Using the property of logarithms that
ln
(
a
b
)
=
b
⋅
ln
(
a
)
\ln(a^b) = b\cdot\ln(a)
ln
(
a
b
)
=
b
⋅
ln
(
a
)
, we can simplify the expression to
(
1
3
)
⋅
ln
(
e
2
)
(\frac{1}{3})\cdot\ln(e^2)
(
3
1
)
⋅
ln
(
e
2
)
.
Further simplify expression:
Since
ln
(
e
)
\ln(e)
ln
(
e
)
is equal to
1
1
1
, we can further simplify the expression to
(
1
3
)
⋅
2
⋅
ln
(
e
)
(\frac{1}{3})\cdot 2\cdot \ln(e)
(
3
1
)
⋅
2
⋅
ln
(
e
)
.
Multiply to get final expression:
Now, we multiply
2
2
2
by
1
3
\frac{1}{3}
3
1
to get
(
2
3
)
⋅
ln
(
e
)
(\frac{2}{3})\cdot\ln(e)
(
3
2
)
⋅
ln
(
e
)
.
Final answer:
Finally, since
ln
(
e
)
\ln(e)
ln
(
e
)
equals
1
1
1
, we multiply
2
3
\frac{2}{3}
3
2
by
1
1
1
to get the final answer.
