7=x√3 Solve this equation for X without using a calculator [closed]

7=x√3

solve for x

DO NOT find the decimal answer of the √3 but keep it as a square root simplifying completely

(this is from a 30, 60, 90 triangle)

After an exhaustive analysis, which took me fully into the realms of differential equations and general relativity, I have come to the tentative conclusion that $$x=\frac{7}{\sqrt{3}}$$ ...And I did that without converting to a decimal.

Although I understand the sentiment, don't be too quick to dismiss the value of learning to rationalize the denominator. The OP is obviously just starting his mathematical journey. If you have ever taught calculus, you must know that students who already know about this and are comfortable with it have no problem whatsoever computing the derivative of $1/\sqrt x$ from basics (as a limit), while those who never learned it struggle the most with this very elementary procedure. It is pedagogically invaluable. –  MPW Apr 8 at 1:09
@MPW It is useful. I just don't like it when ideas are presented in a vacuum. There's no point in making him/her change $1/\sqrt{3}$ to $\sqrt{3}/3$ if they're just doing algebra. It should be taught when it actually becomes relevant, such as in manipulating limits as you said. And I was being a little humorous obviously, no harm meant... –  user140943 Apr 8 at 1:13
