\(a,\sqrt{2,5}.\sqrt{30}.\sqrt{48}\)

\(=\sqrt{2,5.30.48}\)

\(=\sqrt{3600}\)

\(=60\)

\(b,\sqrt{\left(\sqrt{3}-2\right)^2}=\sqrt{3}-2\)

\(c,\sqrt{3\frac{1}{16}.2\frac{14}{25}.2\frac{34}{81}}\)

\(=\sqrt{\frac{49}{16}.\frac{64}{25}.\frac{196}{81}}\)

\(=\sqrt{\frac{49}{16}}.\sqrt{\frac{64}{25}}.\sqrt{\frac{196}{81}}\)

\(=\frac{7}{4}.\frac{8}{5}.\frac{14}{9}\)

\(=\frac{196}{45}\)
