Answer 2

1. The required option D) $\dfrac{1}{8} \dfrac{b^3}{a^2}$ is correct.

2. The required "option C) $\dfrac{(x-2)}{(x+3)}$"is correct.

Step-by-step explanation:

1. The given expression:

$\dfrac{7ab^5}{56a^3b^2}$

To find, the value of the given expression = ?

∴ $\dfrac{7ab^5}{56a^3b^2}$

$=\dfrac{7}{56} \dfrac{b^3}{a^2}$

$=\dfrac{1}{8} \dfrac{b^3}{a^2}$

Thus, the required option D) $\dfrac{1}{8} \dfrac{b^3}{a^2}$ is correct.

2. The given expression:

$\dfrac{(x-3)(x-2)}{(x+3)(x-3)}$

To find, the value of the given expression = ?

∴ $\dfrac{(x-3)(x-2)}{(x+3)(x-3)}$

(x -3) is cancel.

$=\dfrac{(x-2)}{(x+3)}$

Thus, the required "option C) $\dfrac{(x-2)}{(x+3)}$"is correct.
