\( \left. \begin{array} { l } { \frac { 3 } { 4 } - \frac { 2 } { 5 } = \frac { ( 5 ) ( 3 ) } { ( 5 ) ( 4 ) } - \frac { ( 4 ) ( 2 ) } { ( 4 ) ( 5 ) } = \frac { 15 } { 20 } - \frac { 8 } { 20 } = \frac { - } { 20 } } \\ { \frac { 1 } { 4 } + \frac { 1 } { 2 } = \frac { 1 } { 4 } + \frac { ( L ) ( 1 ) } { ( - ) ( 2 ) } = \frac { 1 } { 4 } + \frac { 2 } { 4 } = - } \end{array} \right. \)

\( \sqrt {(-13)^{2}-5^{2}}.\sqrt [3]{-27} \)
