Решебник по математике 6 класс Мерзляк ФГОС Задание 106

\[\boxed{\mathbf{106\ (106).}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 12 = 2^{2} \cdot 3\]

\[2)\ 42 = 2 \cdot 3 \cdot 7\]

\[3)\ 216 = 2^{3} \cdot 3^{3}\]

\(\ \)

\[4)\ 450 = 2 \cdot 3^{2} \cdot 5^{2}\]

\[5)\ 920 = 2^{3} \cdot 5 \cdot 23\]

\[6)\ 2280 = 2^{3} \cdot 3 \cdot 5 \cdot 19\]

\[7)\ 10\ 850 = 2 \cdot 5^{2} \cdot 7 \cdot 31\]

\[\boxed{\mathbf{106}.}\]

\[1)\ 73y - y - 22y + 40 = 190\]

\[50y = 190 - 40\]

\[50y = 150\]

\[y = 150\ :50\]

\[y = 3.\]

\[2)\ 56 + 72\ :(x - 12) = 60\]

\[72\ :(x - 12) = 60 - 56\]

\[72\ :(x - 12) = 4\]

\[x - 12 = 72\ :4\]

\[x - 12 = 18\]

\[x = 18 + 12\]

\[x = 30.\]
