Find the value of the expression log27√3

slega [8]

$\log _{ 27 }{ \left( \sqrt { 3 } \right) } \\ \\ =\frac { \log _{ 3 }{ \left( \sqrt { 3 } \right) } }{ \log _{ 3 }{ \left( 27 \right) } }$

$\\ \\ =\frac { \log _{ 3 }{ \left( { 3 }^{ \frac { 1 }{ 2 } } \right) } }{ 3 } \\ \\ =\frac { \frac { 1 }{ 2 } \log _{ 3 }{ 3 } }{ 3 } \\ \\ =\frac { \frac { 1 }{ 2 } }{ 3 }$

$\\ \\ =\frac { 1 }{ 2 } \cdot \frac { 1 }{ 3 } \\ \\ =\frac { 1 }{ 6 }$
