$\sqrt{36 * 81} = \sqrt{36} * \sqrt{81} = 6 * 9 = 54$
$\sqrt{900 * 49} = \sqrt{900} * \sqrt{49} = 30 * 7 = 210$
$\sqrt{16 * 0,25} = \sqrt{16} * \sqrt{0,25} = 4 * 0,5 = 2$
$\sqrt{9 * 1,69} = \sqrt{9} * \sqrt{1,69} = 3 * 1,3 = 3,9$
$\sqrt{0,36 * 1,21} = \sqrt{0,36} * \sqrt{1,21} = 0,6 * 1,1 = 0,66$
$\sqrt{5^2 * 3^6} = \sqrt{5^2} * \sqrt{3^6} = \sqrt{5^2} * \sqrt{(3^3)^2} = |5| * |3^3| = 5 * |27| = 5 * 27 = 135$
$\sqrt{4^4 * 3^2} = \sqrt{4^4} * \sqrt{3^2} = \sqrt{(4^2)^2} * \sqrt{3^2} = |4^2| * |3| = |16| * 3 = 16 * 3 = 48$
$\sqrt{2^6 * 5^2} = \sqrt{2^6} * \sqrt{5^2} = \sqrt{(2^3)^2} * \sqrt{5^2} = |2^3| * |5| = |8| * 5 = 8 * 5 = 40$
$\sqrt{2,25 * 0,04 * 1600} = \sqrt{2,25} * \sqrt{0,04} * \sqrt{1600} = 1,5 * 0,2 * 40 = 0,3 * 40 = 12$
$\sqrt{13\frac{4}{9}} = \sqrt{\frac{121}{9}} = \frac{\sqrt{121}}{\sqrt{9}} = \frac{11}{3} = 3\frac{2}{3}$
$\sqrt{1\frac{7}{9} * \frac{4}{25}} = \sqrt{\frac{16}{9}} * \sqrt{\frac{4}{25}} = \frac{\sqrt{16}}{\sqrt{9}} * \frac{\sqrt{4}}{\sqrt{25}} = \frac{4}{3} * \frac{2}{5} = \frac{8}{15}$
$\sqrt{\frac{1}{16} * \frac{9}{25}} = \sqrt{\frac{1}{16}} * \sqrt{\frac{9}{25}} = \frac{\sqrt{1}}{\sqrt{16}} * \frac{\sqrt{9}}{\sqrt{25}} = \frac{1}{4} * \frac{3}{5} = \frac{3}{20}$
