Is this question proper? "Solve $\log_{10}x\in\mathbb{R}$."?

I know that $\log_{10}x\in\mathbb{R}$ means $x\in(0,\infty)$, but can we write "Solve $\log_{10}x\in\mathbb{R}$." as a question alone? Thank you.

    Rather than "solve", maybe you could write "Find all x such that $\log _{10}x \in R$"2012-10-21

Perhaps it would be better to ask, "For what $x$ is $\log_{10} x \in \mathbb{R}$?" When you say "solve" it suggests there are a finite number of solutions, and there aren't finitely many.

    Yes, I mean "infinitely".2012-10-22

"Solve $\log_{10}x$" may make sense if you interpret "solve" as evaluate/simplify. For example: "Solve $\log_{10}100$":

$\log_{10}100=\log_{10}10^2=2$
