\[\boxed{\text{434\ (434).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
Пояснение.
Решение.
\[1)\ 3a + 6b = 3 \cdot (a + 2b).\]
\[2)\ 12m - 16n = 4 \cdot (3m - 4n).\]
\[3)\ 10ck - 15cp =\]
\[= 5c \cdot (2k - 3p).\]
\[4)\ 8ax + 8a = 8a \cdot (x + 1).\]
\[5)\ 5b - 25bc = 5b \cdot (1 - 5c).\]
\[6)\ 14x^{2} + 7x = 7x \cdot (2x + 1).\]
\[7)\ n^{10} - n^{5} = n^{5} \cdot \left( n^{5} - 1 \right).\]
\[8)\ m^{6} + m^{7} = m^{6} \cdot (1 + m).\]
\[9)\ 9x - 27x^{4} = 9x \cdot \left( 1 - 3x^{3} \right).\]
\[10)\ 18y^{5} + 12y^{4} =\]
\[= 6y^{4} \cdot (3y + 2).\]
\[11)\ 56a^{10}b^{6} - 32a^{4}b^{8} =\]
\[= 8a^{4}b^{6} \cdot \left( 7a^{6} - 4b^{2} \right).\]
\[12)\ 36mn^{5} + 63m^{2}n^{6} =\]
\[= 9mn^{5} \cdot (4 + 7mn)\text{.\ \ }\]
