Question

daca 5√27supra 6√3=xsupra3 ,atunci x=

Answer 1

$\frac{5\sqrt{27}}{6 \sqrt{3}} = \frac{x}{3} \to \frac{5\sqrt{3^3}}{6 \sqrt{3}} = \frac{x}{3} \to \frac{5\cdot3\sqrt{3}}{6 \sqrt{3}} = \frac{x}{3} \to \frac{15}{6} = \frac{x}{3} \to x= \frac{3\cdot15}{6}=7.5$

Answer 2

$\frac{5 * \sqrt{27}}{6 * \sqrt{3} } = \frac{x}{3}$
$5 *3 *\sqrt{27} = x * 6 * \sqrt{3}$
$5 *3 *\sqrt{9 * 3} = x * 6 * \sqrt{3}$
$5 *3 * 3*\sqrt{3} = x * 6 * \sqrt{3}$
x = $\frac{5 * 3 * 3}{6} = \frac{15}{2}$ = 7.5
