Answer 1

a)

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

b)

${( + 4)}^{0} = 1$

c)

${( + 6)}^{2} = 6 \times 6 = 36$

d)

${0}^{7} = 0 \times 0 \times 0 \times 0 \times 0 \times 0 \times 0 = 0$

e)

${( + 10)}^{3} = 10 \times 10 \times 10 = 1000$

f)

${( + 9)}^{1} = 9$

g)

${( + 2)}^{4} = 2 \times 2 \times 2 \times 2 = 16$

h)

${( + 2)}^{5} = 2 \times 2 \times 2 \times 2 \times 2 = 32$

i)

${( - 5)}^{2} = ( - 5) \times ( - 5) = 25$

j)

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

k)

${( - 3)}^{3} = ( - 3) \times ( - 3) \times ( - 3) = - 27$

l)

${( - 1)}^{5} = ( - 1) \times ( - 1) \times ( - 1) \times ( - 1) \times ( - 1) = - 1$
