85 * (435 : 5 − 47) = 3400
(63 * 8 + 48) : 3 = 184

Вычисления:
$85 \overset{3}{*} (435 \overset{1}{:} 5 \overset{2}{-} 47) = 3400$
1) 435 : 5 = (400 + 35) : 5 = 400 : 5 + 35 : 5 = 80 + 7 = 87
2) 87 − 47 = 40
3) 85 * 40 = (80 + 5) * 40 = 80 * 40 + 5 * 40 = 3200 + 200 = 3400
 
$(63 \overset{1}{*} 8 \overset{2}{+} 48) \overset{3}{:} 3 = 184$
1) 63 * 8 = (60 + 3) * 8 = 60 * 8 + 3 * 8 = 480 + 24 = 504
2) 504 + 48 = 552
3) 552 : 3 = 184
