Question

find each of the following expressions a,-3/7x×15/9y
b,9x³y×3x²y²
c,2x³y×(-13y²)
d,(-4xyz)×(-2x²y³z⁴)​

Answer 1

Answer:

$a. \frac{ - 3x}{7} \times \frac{15y}{9} = \frac{ - 5xy}{7} \\ b.9 {x}^{3} y \times 3 {x}^{2} {y}^{2} = 27 {x}^{5} {y}^{3} \\ c.2 {x}^{3} y \times - 13{y}^{2} = - 26 {x}^{3} {y}^{3} \\ d. - 4xyz \times - 2 {x}^{3} {y}^{3} {z}^{4} = 8 {x}^{4} {y}^{4} {z}^{5}$
