Question

Выполнить умножение:​

Answer 1

б) $= 0.5a b^{6} * 10 a^{2} b^{2} = 5a^{3} b^{8}$

в) $= -\frac{1}{6} c^{5} a b^{3} * (-6ca b^{3}) = c^{6} a^{2} b^{6}$

Answer 2

$0.5a \times ( - b)^{6} \times 10a^{2} {b}^{2} \\ 0.5ab^{6} \times 10 {a}^{2} {b}^{2} \\ 5a^{3} {b}^{8}$

$\frac{1}{6} \times ( - c)^{5} ab^{ 3} \times ( - 6cab^{3} ) \\ \frac{1}{6} \times ( - c ^{5} )ab ^{3} \times ( - 6ab ^{3} c) \\ {c}^{5} a {b}^{3} a {b}^{3} c \\ {a}^{2} {b}^{6} {c}^{6}$
