Ponieważ:
[tex]\sqrt{3}\approx 1,73\\\\\sqrt{2}\approx1,41[/tex]
Więc:
[tex]a)\ 3\sqrt{3}-2=3\cdot 1,73-2=5,19-2= 3,19\approx \boxed{3,2}\\\\b)\ 5\sqrt{2}-2\sqrt{3}= 5\cdot 1,41-2\cdot 1,73= 7,05-3,46= 3,59\approx\boxed{3,6}\\\\c)\ \sqrt{2}+4\sqrt{3}=1,41+4\cdot 1,73=1,41+6,96=8,33\approx \boxed{8,3}[/tex]
