$\sqrt{9 * 25} = \sqrt{9} * \sqrt{25} = 3 * 5 = 15$
$\sqrt{16 * 2500} = \sqrt{16} * \sqrt{2500} = 4 * 50 = 200$
$\sqrt{0,64 * 36} = \sqrt{0,64} * \sqrt{36} = 0,8 * 6 = 4,8$
$\sqrt{400 * 1,44} = \sqrt{400} * \sqrt{1,44} = 20 * 1,2 = 24$
$\sqrt{0,09 * 0,04} = \sqrt{0,09} * \sqrt{0,04} = 0,3 * 0,2 = 0,06$
$\sqrt{6,25 * 0,16} = \sqrt{6,25} * \sqrt{0,16} = 2,5 * 0,4 = 1$
$\sqrt{6^2 * 3^4} = \sqrt{6^2} * \sqrt{3^4} = \sqrt{6^2} * \sqrt{(3^2)^2} = |6| * |3^2| = 6 * 9 = 54$
$\sqrt{7^2 * 2^8} = \sqrt{7^2} * \sqrt{(2^4)^2} = |7| * |2^4| = 7 * 16 = 112$
$\sqrt{25 * 64 * 0,36} = \sqrt{25} * \sqrt{64} * \sqrt{0,36} = 5 * 8 * 0,6 = 40 * 0,6 = 24$
$\sqrt{0,01 * 0,81 * 2500} = \sqrt{0,01} * \sqrt{0,81} * \sqrt{2500} = 0,1 * 0,9 * 50 = 0,9 * 5 = 4,5$
$\sqrt{\frac{81}{100}} = \frac{\sqrt{81}}{\sqrt{100}} = \frac{9}{10} = 0,9$
$\sqrt{\frac{49}{256}} = \frac{\sqrt{49}}{\sqrt{256}} = \frac{7}{16}$
$\sqrt{3\frac{13}{36}} = \sqrt{\frac{121}{36}} = \frac{\sqrt{121}}{\sqrt{36}} = \frac{11}{6} = 1\frac{5}{6}$
$\sqrt{3\frac{1}{16} * 2\frac{14}{25}} = \sqrt{\frac{49}{16} * \frac{64}{25}} = \sqrt{\frac{49}{16}} * \sqrt{\frac{64}{25}} = \frac{\sqrt{49}}{\sqrt{16}} * \frac{\sqrt{64}}{\sqrt{25}} = \frac{7}{4} * \frac{8}{5} = \frac{7}{1} * \frac{2}{5} = \frac{14}{5} = 2\frac{4}{5}$
$\sqrt{\frac{169}{36 * 81}} = \frac{\sqrt{169}}{\sqrt{36} * \sqrt{81}} = \frac{\sqrt{169}}{\sqrt{36 * 81}} = \frac{13}{6 * 9} = \frac{13}{54}$
$\sqrt{\frac{121 * 256}{25 * 100}} = \frac{\sqrt{121 * 256}}{\sqrt{25 * 100}} = \frac{\sqrt{121} * \sqrt{256}}{\sqrt{25} * \sqrt{100}} = \frac{11 * 16}{5 * 10} = \frac{11 * 8}{5 * 5} = \frac{88}{25} = 3\frac{13}{25} $
