Question

56x³y⁴/z⁵•(-z⁴/16x²y⁶)=

Answer 1

Объяснение:

$\frac{56 {x}^{3} {y}^{4} }{ {z}^{5} } \cdot \frac{ - {z}^{4} }{16 {x}^{2} {y}^{6} } = - \frac{56 {x}^{3} {y}^{4} {z}^{4}}{16 {x}^{2} {y}^{6}z^{5} } = \\ = \frac{7 \cdot \cancel8 \: {{x}^{\cancel3^1}}\cancel{{y}^{4}} \cancel{{z}^{4}}}{2 \cdot \cancel8 \cancel{ {x}^{2}} {y}^{\cancel6^2}z^{\cancel5^1} } = \frac{7x}{2y^2z}$
