Mathematics

$x=\sqrt{3i}$ or $x=-\sqrt{3i}$

Step-by-step explanation:

Rewrite as a system of equations: $x=\sqrt{-3}$ or $x=-\sqrt{-3}$

Rewrite $\sqrt{-a}$ as $\sqrt{a} *\sqrt{-1} :x=\sqrt{3} *&\sqrt{-1}$

Rewrite by definition $i=\sqrt{-1}:x=\sqrt{3i}$

Rewrite $\sqrt{a}$ as $\sqrt{a} *\sqrt{-1} :x=-\sqrt{3} *\sqrt{-1}$

Rewrite by definition $i=\sqrt{-1} :x=-\sqrt{3i}$

Find the union of the solutions: $x=\sqrt{3i}$ or $x=-\sqrt{3i}$

$x=\sqrt{3i}$ or $x=-\sqrt{3i}$
