$296, \quad 370, \quad 629, \quad 3441, \quad 9102, \quad 27084;$

Пошаговое объяснение:

$37 \cdot 8=(30+7) \cdot 8=30 \cdot 8+7 \cdot 8=240+56=296;$

$37 \cdot 10=370;$

$37 \cdot 17=(30+7) \cdot 17=30 \cdot 17+7 \cdot 17=510+119=629;$

$37 \cdot 93=(40-3) \cdot (100-7)=40 \cdot 100-40 \cdot 7-3 \cdot 100+3 \cdot 7=4000-280-300+21=$

$=4000-580+21=3420+21=3441;$

$37 \cdot 246=(40-3) \cdot (250-4)=40 \cdot 250-40 \cdot 4-3 \cdot 250+3 \cdot 4=10000-160-$

$-750+12=10000-910+12=9090+12=9102;$

$37 \cdot 732=(40-3) \cdot (750-18)=40 \cdot 750-40 \cdot 18-3 \cdot 750+3 \cdot 18=30000-720-$

$-2250+54=30000-2970+54=30000-3000+30+54=27000+84=27084;$

$\begin {center}\begin {tabular}{ccccccc}c \quad & \text {8} \quad & \text {10} \quad & \text {17} \quad & \text {93} \quad & \text {246} \quad & \text {732}\\37 \cdot c \quad & \textbf {296} \quad & \textbf {370} \quad & \textbf {629} \quad & \textbf {3441} \quad & \textbf {9102} \quad & \textbf {27084}\\\end {tabular}\end {center}$
