\[\boxed{\text{230\ (230).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
Пояснение.
Решение.
\[6000\ :(20 \cdot 5) \cdot 6 =\]
\[= 6000\ :100 \cdot 6 = 60 \cdot 6 = 360\]
\[1000\ :(90\ :9) \cdot 100 =\]
\[= 1000\ :10 \cdot 100 = 100 \cdot 100 =\]
\[= 10\ 000\]
\[\left( 525 -^{1}238 \right) \cdot^{2}3 = 287 \cdot 3 =\]
\[= 861\]
\[\left( 517 -^{1}450 \right) \cdot^{2}9 = 67 \cdot 9 = 603\]
\[\left( 92{4 -}^{1}207 \right)\ :^{2}3 = 717\ :3 =\]
\[= 239\]
\[\left( 413 +^{1}196 \right){\ :}^{2}7 = 609\ :7 = 87\]
