Question

Carry out the following divisions
(i) $28x^4÷56x$
(ii) $-36y^3÷9y^2$
(iii) $66p{q}^2{r}^3÷11q{r}^2$
(iv) $34x^3{y}^3{z}^3÷51x{y}^2{z}^3$
(v) $12a^8{b}^8÷(-6a^6{b}^4)$

Answer 1

(i) $28x^4÷56x$

$=\frac{28x^4}{56x}$$=\frac{x^3}{2}$

(ii) $-36y^3÷9y^2$

$=\frac{-36y^3}{9y^2}-4y$
(iii) $66p{q}^2{r}^3÷11q{r}^2$
$=\frac{66p{q}^2{r}^3}{11q{r}^2}$$=6pqr$

(iv) $34x^3{y}^3{z}^3÷51x{y}^2{z}^3$
$=\frac{34x^3{y}^3{z}^3}{51x{y}^2{z}^3}$$=\frac{2}{3}{x}^{2}y$
(v) $12a^8{b}^8÷(-6a^6{b}^4)$
$\frac{12a^8{b}^8}{(-6a^6{b}^4)}$$=-2a^2{b}^4$
