Answer 1

$a) \sqrt{ \frac{9}{16}*5 } = \sqrt{ \frac{45}{16} }$
$b) \sqrt{ \frac{9*7}{18} } = \sqrt{ \frac{63}{18} }$
$c) -\sqrt{ \frac{4*7}{25} } =- \sqrt{ \frac{28}{25} }$
$d)- \sqrt{ \frac{16*6}{9} } =- \sqrt{ \frac{96}{9} }$
$e) \sqrt{ \frac{4*42}{9} } = \sqrt{ \frac{168}{9} }$
$f)- \sqrt{ \frac{9}{64}* \frac{2}{3} } = \sqrt{ \frac{3}{32} }$
$g)- \sqrt{9* \frac{1}{3} } =- \sqrt{3}$
$h) \sqrt{ \frac{2}{5}*2 } = \sqrt{ \frac{4}{5} }$
$i)- \sqrt{ \frac{15}{18}* \frac{36}{25} } =- \sqrt{ \frac{6}{5} }$
$j)- \sqrt{ \frac{4}{9} *6} =- \sqrt{ \frac{8}{3} }$
$k) \sqrt{ \frac{1}{144}* \frac{4}{15} } = \sqrt{ \frac{1}{540} }$
