Answer 1

$\sqrt{36 \times 121 \times 25} = \sqrt{ {6}^{2} \times {11}^{2} \times {5}^{2} } = 6 \times 11 \times 5 = 30 \times 11 = 330$

$\sqrt{1 \frac{9}{16} } = \sqrt{ \frac{25}{16} } = \sqrt{ \frac{5 {}^{2} }{4 {}^{2} } } = \frac{5}{4} = 1.25$

$( \sqrt{17} + 3)(\sqrt{17} - 3) = ( \sqrt{17} ) {}^{2} - 9 = 17 - 9 = 8$
