Question

-9y×(2/3xy^4)=памагитэ☆☆☆

Answer 1

Объяснение:

$- 9y \times ( \frac{2}{3} xy {}^{4} ) = - 9y \times \frac{2}{3} xy {}^{4} = - 3y \times 2xy {}^{4} = - 6xy {}^{5}$

Answer 2

или так:

$- 9y \times \frac{2}{3x {y}^{4} } = - \frac{9y \times 2}{3x {y}^{4} } = - \frac{2 \times 3 \times 3 \times y}{3 \times x \times y \times {y}^{3} } = - \frac{2 \times 3}{x \times {y}^{3} } = - \frac{6}{x {y}^{3} }$
