Answer 1

Vamos primeiramente resolver as expressões:

A.

$5 \times {3}^{3} - 2 \\ 5 \times 27 - 2 \\ 135 - 2 \\ 133$

$(15 - 7) \times (8 + 4) \\ 8 \times 12 \\ 96$

$452 - 13 \times 25 \\ 452 - 325 \\ 127$

B.

$446 - 7 \times 50 \\ 446 - 350 \\ 96$

${2}^{7} - 1 \\ 128 - 1 \\ 127$

${5}^{2} + 4 \times {3}^{3} \\ 25 + 4 \times 27 \\ 25 + 108 \\ 133$

Sendo assim temos:

I.5×3^3-2=5^2+4×3^3

II.(15-7)×(8+4)=446-7×50

III.452-13×25=2^7-1
