(-8.3)^0
-(10)^-1
1/a^-2

Answers

Answer 1
Answer: { \left( -2 \right) }^( -5 )=\frac { 1 }{ { \left( -2 \right) }^( 5 ) } =-\frac { 1 }{ 32 } \n \n { \left( -8.3 \right) }^( 0 )=1\n \n -{ 10 }^( -1 )=-\frac { 1 }{ { 10 }^( 1 ) } =-\frac { 1 }{ 10 } \n \n \frac { 1 }{ { a }^( -2 ) } =\frac { 1 }{ \frac { 1 }{ { a }^( 2 ) } } =\frac { 1 }{ 1 } / \frac { 1 }{ { a }^( 2 ) } =\frac { 1 }{ 1 } * \frac { { a }^( 2 ) }{ 1 } ={ a }^( 2 )
