Question

Simplify: $(-57x^2{y}^3{z}^2)÷(-19xyz)$

• A. $-3x{y}^{2}z$
• B. $3xyz$
• C. $3x{y}^{2}z$
• D. $3x^2{y}^2{z}^2$

Answer 1

Answer: (C)

$3x{y}^{2}z$

We need to simplify $(-57x^2{y}^3{z}^2)÷(-19xyz)$

$=\frac{(-57x^2{y}^3{z}^2)}{(-19xyz)}=3\times \frac{x^2}{x}\times \frac{y^3}{y}\times \frac{z^2}{z}$

$=3x{y}^{2}z$
