Answer 1

Răspuns:

$b=0,75*\sqrt{72}-\frac{\sqrt{32}}{8}+0,1(6)* \sqrt{18}$

$b=\frac{75}{100} *6\sqrt{2}-\frac{4\sqrt{2}}{8}+\frac{15}{90}* 3\sqrt{2}$

$b=\frac{3}{4} *6\sqrt{2}-\frac{\sqrt{2}}{2}+\frac{1}{6}* 3\sqrt{2}$

$b=\frac{9\sqrt{2}}{2}-\frac{\sqrt{2}}{2}+\frac{\sqrt{2}}{2}$

$b=\frac{9\sqrt{2}}{2}$
