(-6) 3 =
d) (-2) 9 =​

me ajudem por favor

Answer 1

$\color{blue}a)( + 4) {}^{3} = ( + 4) \times ( + 4) \times ( + 4) = \color{red} + 64$

$\color{blue}b)( - 3) {}^{4} = ( - 3) \times ( - 3) \times ( - 3) \times ( - 3) = \color{red} + 81$

$\color{blue}c)( + 5) {}^{4} = ( + 5) \times ( + 5) \times ( + 5) \times ( + 5) = \color{red} + 625$

$\color{blue}d)( - 2) {}^{9} = ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) = \color{red} - 512$

$\color{blue}e)( + 3) {}^{5} = ( + 3) \times ( + 3) \times ( + 3) \times ( + 3) \times ( + 3) = \color{red} + 243$

$\color{blue}f)( - 6) {}^{3} = ( - 6) \times ( - 6) \times ( - 6) = \color{red} - 216$

Explicação passo-a-passo :

Regra de sinais :

Mais (+) com mais (+) = +

Menos (-) com menos (-) = +

Mais (+) com menos (-) = -

Menos (-) com mais (+) = -
