Question

(-1)⁵
(-2)² + (0,1)-²​

Answer 1

(-1)⁵   =  -1  

(-2)² + (0,1)-²​  TEMOS QUE TRANSFORMAR O DECIMAL EM FRAÇÃO.

               0,1  . 10 = 1  ENTÃO FICARÁ      1    

                                                                 10

$(-2)^{2} + (\frac{1}{10} )^{-2} = 4 + 10^{2} = 4 + 100 = 104$

O certo da tua conta pode ser

$\frac{(1)^{5} }{(-2)^{2} } + (0,1)^{-2} =\\\\\\\frac{1}{4} + (\frac{1}{10} )^{-2} =\\\\\frac{1}{4} +10^{2} =\\\\\frac{1}{4} + 100 =\\\\\frac{1+400}{4} =\\\\\frac{401}{4}$  

ou    

$\frac{(-1)^{5} }{-2^{2} } + (0,1)^{-2} =\\\\\\\frac{-1}{-4} + (\frac{1}{10} )^{-2} =\\\\\frac{-1}{-4} +10^{2} =\\\\\frac{-1}{-4} + 100 =\\\\\frac{-1-400}{-4} =\\\\\frac{-401}{-4}=\\\\\frac{401}{4}$
