\[\boxed{\text{326\ (326).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

Пояснение.

Решение.

\[1)\ \overline{\text{cba}} = 100c + 10b + a.\]

\[2)\ \overline{\text{abc}} - \overline{\text{ab}} =\]

\[= 100a + 10b + c - 10a - b =\]

\[= 100a + 9b - 10a + c =\]

\[= 90a + 9b + c.\]

\[3)\ \overline{a0c} + \overline{\text{ac}} =\]

\[= 100a + c + 10a + c =\]

\[= 110a + 2c.\ \ \]

\[\boxed{\text{326.}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]

\[1)\ 24\ :3 = 8\]

\[3^{24} = \left( 3^{3} \right)^{8}\]

\[2)\ 24\ :12 = 2\ \]

\[3^{24} = \left( 3^{12} \right)^{2}\]

\[3)\ 24\ :2 = 12\]

\[3^{24} = \left( 3^{2} \right)^{12} = 9^{12}\]

\[4)\ 24\ :4 = 6\]

\[3^{24} = \left( 3^{4} \right)^{6} = 81^{6}\]
