Answer 1

Step-by-step explanation:

$= > - 12 \times ( - 2) \times (1) {}^{3} (4 \times ( - 2) {}^{2} \times 1 {}^{2} + \frac{3}{4} \times - 2 {}^{2} \times 1 {}^{2}$

$= > - 12 \times ( - 2) \times4 \times ( - 2) {}^{2} \times 1 {}^{2} + \frac{3}{4} \times - 2 {}^{2} \times 1 {}^{2}$

$= > 24 \times 4 \times 4 \times 1 + \frac{3}{4} \times 4 \times 1$

$= > 24 \times 16 + 3$
