x: 4√3= 6√2: 3√6
x:4√3= [tex] \frac{ 6\sqrt{2} }{3 \sqrt{6} } , rationalizam=\ \textgreater \ \frac{6 \sqrt{12} }{18} = \frac{6*2 \sqrt{3} }{18} = \frac{ 2\sqrt{3} }{3} [/tex]
x:4√3= [tex] \frac{ 2\sqrt{3} }{3} [/tex] |*4√3
x= [tex] \frac{ 2\sqrt{3}* 4\sqrt{3} }{3} = \frac{8*3}{3} =8=\ \textgreater \ x=8[/tex]
