Answer

no real number solution

Work Step by Step

$\sqrt (2x)=-4$ Without needing to solve, we can see that this equation will have no real number solution. We are asked to find a value of x such that the term $\sqrt (2x)$ will equal -4. That being said, we know that the square root of a negative number is not a real number, as there is no number $a$ such that $a^{2}=-4$.
