\[\boxed{\text{385\ (385).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
Пояснение.
Решение.
\[\left( 720 +^{1}9080 \right) \cdot^{2}3 = 9800 \cdot 3 =\]
\[= 29\ 400\]
\[\left( 5010 -^{1}430 \right) \cdot^{2}9 = 41\ 220\]
\[(130 - 50) \cdot (42 - 35) =\]
\[= 80 \cdot 7 = 560\]
\[(210 + 90)\ :(60 - 57) =\]
\[= 300\ :3 = 100\]
\[6 \cdot 8\ :3 = 48\ :3 = 16\]
\[8 \cdot 9\ :2 = 72\ :2 = 36\]
