me ajudem por favor

Answer 1

Resposta:

a)

$3 \times {2}^{3} = {2}^{3} = 8 \\ 8 \times 3 = 24$

b)

$100 \div {5}^{2} = {5}^{2} = 5 \times 5 = 25 \\ 100 \div 25 = 4$

c)

${1}^{2} ( - 3) {}^{2} + 7 \times {8}^{0} = \\ 1 - 9 + 7 \times 1 = pronto \: agr \: e \: so \: resolver$

2 a)

${3}^{2} + {2}^{3} = 3 \times 3 = 9 \\ 2 \times 2 \times 2 = \\ 9 + 8 = 17$

Espero ter Ajudado me siga sigo de volta!!!
