Answer 1

$\Large\sf{\underline{\underline{Question:-}}}$

$( - \dfrac{2}{7} u {}^{4} v) \times ( \dfrac{- 14}{5} uv {}^{3} ) \times (\dfrac{- 3}{4} u {}^{2} v {}^{3} )$

$\Large\sf{\underline{\underline{Solution:-}}}$

$( - \dfrac{2}{7} u {}^{4} v) \times ( \dfrac{- 14}{5} uv {}^{3} ) \times (\dfrac{- 3}{4} u {}^{2} v {}^{3} )$

= $( \dfrac{2}{\cancel{7}} u {}^{4} v \times \dfrac{\cancel{14}}{5} uv {}^{3} ) \times ( \dfrac{- 3}{4} u {}^{2} v {}^{3} )$

= $\dfrac{4}{5} u {}^{5} v {}^{4} \times ( \dfrac{- 3}{4} u {}^{2} v {}^{3} )$

= $( - \dfrac{\cancel{4}}{5} u {}^{5} v {}^{4} \times \dfrac{3}{\cancel{4}} u {}^{2} v {}^{3} )$

= $- \dfrac{3}{5} u {}^{7} v {}^{7}$

Answer 2

Answer:

$\frac{-3}{5}{u}^{7}{v}^{7}$

Step-by-step explanation:

$( - \frac{2}{7} u {}^{4} v) \times ( \frac{ - 14}{5} uv {}^{3} ) \times (\frac{ - 3}{4} u {}^{2} v {}^{3} ) \\ = \frac{-3}{5}{u}^{7} {v}^{7}$
