Question

Escreva cada potenciação a seguir na forma de multiplicação e calcule a potência:
a) 2⁶ =
b) (-3) ⁴=
c) -5² =
d) 7³ =
e) (-6)³=
f) (-2)⁸ =​

Answer 1

a)

$\sf{ {2}^{6} = 2 \times 2 \times 2 \times 2 \times 2 \times 2 = \fcolorbox{red}{aqua}{64}}$

b)

$\sf{ {( - 3)}^{4} = ( - 3) \times ( - 3) \times ( - 3) \times ( - 3) =\fcolorbox{red}{aqua}{81} }$

c)

$\sf{ { - 5}^{2} = - 5 \times 5 = \fcolorbox{red}{aqua}{ - 25}}$

d)

$\sf{ {7}^{3} = 7 \times 7 \times 7 = \fcolorbox{red}{aqua}{343}}$

e)

$\sf{ {( - 6)}^{3} = ( - 6) \times ( - 6) \times ( - 6) = \fcolorbox{red}{aqua}{ - 216} }$

f)

$\sf{ {( - 2)}^{8} = ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) =\fcolorbox{red}{aqua}{256} }$
