Question

Me ajudem com essas duas questões por favor urgenteee!!!!

Answer 1

13)
             $x^2.2=x \sqrt{8} \\ \\ \frac{x^2}{x} = \frac{ \sqrt{8} }{2} \\ \\ x= \frac{ \sqrt{4x2} }{2} \\ \\ x= \frac{2 \sqrt{2} }{2} \\ \\ x= \sqrt{2}$

14)
             $\sqrt{8} x^2=x\sqrt{12 } \\ \\ \frac{x^2}{x} = \frac{ \sqrt{12} }{ \sqrt{8} } \\ \\ x= \frac{2 \sqrt{3} }{2 \sqrt{2} } \\ \\ x= \frac{ \sqrt{3}. \sqrt{2} }{( \sqrt{2})^2 } \\ \\ x= \frac{ \sqrt{3x2} }{2} \\ \\ = \frac{ \sqrt{6} }{2}$
