(3⁷⁵-3⁷⁴-3⁷³):5

2⁰+2¹+2²+2³+2⁴×5
2³+3³+4³+5³-6³
5×6²+7²×8-999:9​​

Answer 1

Răspuns:

${2}^{38} \times ( {2}^{2} - 2 - 1) = {2}^{38} \times 1 = {2}^{38}$

${3}^{73} \times ( {3}^{2} - 3 - 1) \div 5 = {3}^{73} \times 5 \div 5 = {3}^{73} \times 1 = {3}^{73}$

$1 + 2 + 4 + 8 + 16 \times 5 = 15 + 16 \times 5 = 5 \times (3 + 16) = 5 \times 19 = 95$

$8 + 27 + 64 + 125 - 216 = 8$

$5 \times 36 + 49 \times 8 - 111 = 180 + 392 - 111 = 572 - 111 = 461$
