Answer 1

Resposta:

a)

$( + 3)^{2}= \\ ( + 3) \times ( + 3) = \\ + 9$

b)

$( + 5)^{3} = \\ ( + 5) \times (+ 5) \times ( + 5) = \\ + 125$

c)

${( + 7)}^{2} = \\ ( + 7) \times ( + 7) = \\ + 49$

d)

$( - 11)^{2} = \\ ( - 11) \times ( - 11) = \\ +121$

e)

$( - 5)^{3} = \\ ( - 5) \times ( - 5) \times (- 5) = \\ - 125$

f)

${( - 3)}^{4} = \\ ( - 3) \times ( - 3) \times ( - 3) \times ( - 3) = \\ + 81$

g)

$( - 1)^{6} = \\ ( - 1) \times ( - 1) \times ( - 1) \times \\ ( - 1) \times ( - 1) \times ( - 1) = \\ + 1$

h)

${( - 2)}^{8} = \\ ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) \times \\ ( - 2) \times ( - 2) \times ( - 2) \times ( - 2) = \\ + 256$

i)

$( - 9)^{0} = \\ 1$

j)

${( + 6)}^{1} = \\ + 6$
