Question

n=3, 5+2×{47, 45-0, 3×[4, 2+4×(21, 5-5, 658÷4, 6)]} va rog sa dați răspunsul întreg dacă se poate

Answer 1

$5 + 2 \times (47.45 - 0.3 \times (4.2 + 4 \times (21.5 - 5.658 + 4.6)))$
$5 + 2 \times (47.45 - 0.3(4.2 + 4(21.5 - 1.23))$
$5 + 2(47.45 - 0.3(4.2 + 4 \times 20.27))$
$5 + 2(47.45 - 0.3(4.2 + 81.08))$
$5 + 2(47.45 - 0.3 \times 85.28)$
$5 + 2(47.45 - 25.584)$
$5 + 2 \times 21.866$
$5 + 43.732$
$= 48.732$
