Explicação passo-a-passo:

a)

${2}^{8} = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 = 256$

b)

${13}^{3} = 13 \times 13 \times 13 = 2197$

c)

$92 + 4 = 96$

d)

$(4 \times 100) + 5 = 405$

e)

$[5 \times 1 + 7(81 - 80)] = [5 + 7 \times 1] = 5 + 7 = 12$

f)

$(125 \times 3) = 375$

g)

$(4 \times 8) \times 10 = 32 \times 10 = 320$

h)

$15 \times 15 = 225$

i)

${4 \times [800 - {(9 \times 2 + 10)}^{2}]} = {4 \times[800 - {(18 + 10)}^{2}]} = {4 \times [800 - {(28)}^{2} ]} = {4 \times [800 - 784]} = {4 \times [16]} = 64$

j)

$5 \times 10000 = 50000$

k)

$100000 \times 7 = 700000$
