MCQ
Tick $(\checkmark)$ the correct answer: $8a^2b^3÷ (-2ab) = ?$
- A$ 4 a b^2 $
- B$ 4 a^2 b $
- ✓$ -4 a b^2 $
- D$ -4 a^2 b $
✓
Answer
Correct option: C.
$ -4 a b^2 $
$8\text{a}^2\text{b}^3\div(-2\text{ab})$
$\Rightarrow\frac{8\text{a}^2\text{b}^3}{-2\text{ab}}$
$\Rightarrow-4\text{a}^{2-1}\text{b}^{3-1}$
$\Rightarrow\frac{8\text{a}^2\text{b}^3}{-2\text{ab}}$
$\Rightarrow-4\text{a}^{2-1}\text{b}^{3-1}$
