2 1/4 b²c⁵d³×(-3 1/3 b³ c⁴ d⁷)​

Answer 1

Ответ:

$- \frac{15}{2} \times {b}^{5} \times {c}^{9} \times {d}^{10}$

Объяснение:

$2 \times \frac{1}{4} \times {b}^{2} {c}^{5} {d}^{3} \times ( - 3 \times \frac{1}{3} \times {b}^{3} {c}^{4} {d}^{7} ) = \frac{9}{4} {b}^{2} {c}^{5} {d}^{3} ( - \frac{10}{3} {b}^{3} {c}^{4} {d}^{7} ) = - \frac{3}{2} {b}^{2} {c}^{5} {d}^{3} \times 5 {b}^{3} {c}^{4} {d}^{7} = - \frac{15}{2} \times {b}^{5} {c}^{9} {d}^{10}$
