Question 94 (iv)

Carry out the following division:

$-121p^3{q}^3{r}^3÷(-11x{y}^2{z}^3)$

Answer 1

$-121p^3{q}^3{r}^3÷(-11x{y}^2{z}^3)=\frac{-121p^3{q}^3{r}^3}{(-11x{y}^2{z}^3)}\frac{-11\times 11\times p\times p\times p\times q\times q\times q\times r\times r\times r}{-11\times x\times y\times y\times z\times z\times z}=\frac{11p^3{q}^3{r}^3}{x{y}^2{z}^3}$
