упростите выражение: 232) (7√3 + 14√48 - √148) : 2√3 ; 233) 2√20 + 1,5√28 + √45 - √63 ;...

$\frac{7\sqrt{3}+14\sqrt{48}-\sqrt{148}}{2\sqrt{3}}=\frac{7\sqrt{3}+56\sqrt{3}-2\sqrt{37}}{2\sqrt{3}}=\frac{63\sqrt{3}-2\sqrt{37}}{2\sqrt{3}}=31,5-\sqrt{\frac{37}{3}}$

$2\sqrt{20}+1,5\sqrt{28}+\sqrt{45}-\sqrt{63}=4\sqrt{5}+3\sqrt{7}+3\sqrt{5}-3\sqrt{7}=7\sqrt{5}$

$\frac{2\sqrt{\frac{2}{3}}-8\sqrt{\frac{3}{8}}+4\sqrt{\frac{3}{2}}}{\sqrt{\frac{2}{3}}}= \frac{2\sqrt{\frac{2}{3}}-4\sqrt{\frac{12}{8}}+4\sqrt{\frac{3}{2}}}{\sqrt{\frac{2}{3}}}= \frac{2\sqrt{\frac{2}{3}}}{\sqrt{\frac{2}{3}}}=2$
