Question

Aflati numarul real x , stiind ca x/2√3 = 8√3/x .

Answer 1

$\frac{x}{2 \sqrt{3} }= \frac{8 \sqrt{3} }{x} \Rightarrow x^2=2*8* \sqrt{3} * \sqrt{3} \Longleftrightarrow x^2=16*3 \Longleftrightarrow x^2=48 \\ \Rightarrow x= \sqrt{48} \Longleftrightarrow x=4 \sqrt{3}$

$PROBA: \\ \frac{4 \sqrt{3} }{2 \sqrt{3} } = \frac{8 \sqrt{3} }{4 \sqrt{3} } = 2$
