Answer:

see explanation

Step-by-step explanation:

Given

- ( $\frac{2}{5}$ )²

The negative is outside the bracket and is not squared, that is

= - $\frac{2}{5}$ × $\frac{2}{5}$

= - $\frac{2(2)}{5(5)}$ = - $\frac{4}{25}$

Given

$\frac{5^3}{3}$ = $\frac{5(5)(5)}{3}$ = $\frac{125}{3}$

Answer:

(D) $3 \pm i\sqrt{3}$

Step-by-step explanation:

We can solve this using the quadratic formula, where a is 1, b is -6, and c is 12.

$\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\\frac{-(-6)\pm\sqrt{6^2-4\cdot1\cdot12}}{2\cdot1}\\\\\frac{6\pm\sqrt{36-48}}{2}\\\\\frac{6\pm\sqrt{-12}}{2}\\\\\frac{6\pm i\sqrt{12}}{2}\\\\3\pm i\sqrt{3}\\\\$

Hope this helped!
