Explicação passo-a-passo:
[tex]2 {}^{ - 1} = \frac{1}{2} = 0.5[/tex]
[tex]2 {}^{ - 5} = \frac{1}{2 {}^{5} } = \frac{1}{32 } = 0.03125[/tex]
[tex]( - 2) {}^{ - 2} = \frac{1}{2 {}^{2} } = \frac{1}{4} = 0.25[/tex]
[tex] - 2 {}^{ - 4} = - \frac{1}{2 {}^{4} } = - \frac{1}{16} = - 0.0625[/tex]
[tex] - ( - 4) { }^{ - 3} = \frac{1}{4 {}^{3} } = \frac{1}{64} = 0.015625[/tex]
[tex] - ( - 10) {}^{ - 1} = \frac{1}{10} = 0.1[/tex]
[tex]10 {}^{ - 3} = \frac{1}{1000} = 0.001[/tex]
[tex] 5 {}^{ - 2} = \frac{1}{25} = 0.04[/tex]
