[tex]{ \left( -2 \right) }^{ -5 }=\frac { 1 }{ { \left( -2 \right) }^{ 5 } } =-\frac { 1 }{ 32 } \\ \\ { \left( -8.3 \right) }^{ 0 }=1\\ \\ -{ 10 }^{ -1 }=-\frac { 1 }{ { 10 }^{ 1 } } =-\frac { 1 }{ 10 } \\ \\ \frac { 1 }{ { a }^{ -2 } } =\frac { 1 }{ \frac { 1 }{ { a }^{ 2 } } } =\frac { 1 }{ 1 } \div \frac { 1 }{ { a }^{ 2 } } =\frac { 1 }{ 1 } \times \frac { { a }^{ 2 } }{ 1 } ={ a }^{ 2 }[/tex]
