Answer 1

$frac{ sqrt{40} }{ sqrt{10} } = sqrt{ frac{40}{10} } = sqrt{4} = 2$
$sqrt{5 frac{4}{9} times 11 frac{14}{25} } = sqrt{ frac{49}{9} times frac{289}{25} } = sqrt{ frac{49}{9} } times sqrt{ frac{289}{25} } = frac{7}{3} times frac{17}{5} = frac{119}{15} = 7 frac{14}{15}$
$sqrt{ frac{9}{16} times {5}^{2} } = frac{3}{4} times 5 = frac{15}{4} = 3 frac{3}{4} = 3.75$
${ (sqrt{3} )}^{2} times sqrt{5} = 3 sqrt{5}$
$5 sqrt{3} = sqrt{25 times 3} = sqrt{75}$
$7 sqrt{2} = sqrt{49 times 2} = sqrt{98}$
$2 sqrt{5} = sqrt{4 times 5} = sqrt{20}$
$3 sqrt{7} = sqrt{9 times 7} = sqrt{63}$ [/tex]7 sqrt{3} + 56 sqrt{3} - 147 = 2 sqrt{3} \ 61 sqrt{3}= 147[/tex]
