Answer 2

Answer:

If it helps (and I am sure it will help) then mark me as brainliest.

Step-by-step explanation:

(i)

${( - 4)}^{2} - 4 \\ = 16 - 4 \\ = 12$

(ii)

$\frac{8( - 4) + 6}{2} \\ = \frac{ - 32 + 6}{2} \\ = - 13$

(iii)

$2 {( - 4)}^{2} + 4( - 4) - 2 \\ = 32 - 16 - 2 \\ = 14$

(iv)

$\frac{3( - 4)}{4} + 8 \\ = - 3 + 8 \\ = 5$

(v)

$6 {( - 4)}^{3} + 2 {( - 4)}^{2} - 4( - 4) + 2 \\ = - 384 + 32 + 16 + 2 \\ = - 334$

(vi)

$\frac{6 {( - 4)}^{2} }{12} - \frac{6( - 4)}{3} + 4 \\ = 8 + 8 + 4 \\ = 20$
