Question

Умоляю, помогите, нужно упростить, номер19(б)

Answer 1

$15\sqrt{1,04} =\sqrt{15^{2}*1,04 } =\sqrt{225*1,04} =\sqrt{234} =\sqrt{26*9} =3\sqrt{26} \\\frac{3}{4} \sqrt{5\frac{5}{9} } =\sqrt{(\frac{3}{4})^{2}*5\frac{5}{9}} =\sqrt{\frac{9}{16}*\frac{50}{9}  } =\sqrt{\frac{50}{16} } =\frac{5\sqrt{2} }{4} =1,25\sqrt{2} \\6\sqrt{\frac{1}{18} } =\sqrt{6^{2}*\frac{1}{18}  } =\sqrt{2} \\5\sqrt{0,02} =\sqrt{5^{2}*0,02 } =\sqrt{0,5} =\frac{1}{\sqrt{2} } \\\sqrt{300} =10\sqrt{3} \\\\[tex]3\sqrt{26} -1,25\sqrt{2} +\sqrt{2} -\frac{1}{\sqrt{2} } +10\sqrt{3} =3\sqrt{26} -0,25\sqrt{2}  -\frac{1}{\sqrt{2} } +10\sqrt{3}=3\sqrt{26} -0,75\sqrt{2} +10\sqrt{3} .$
