3. √98/7
4. √648/18
5. √675/15
6. √875/5
7. √216/6
8. √486/9
9. √1280/16

Answer 1

$frac{ sqrt{726} }{11} = frac{11 sqrt{6} }{11} = sqrt{6 }$
$frac{ sqrt{432} }{12} = sqrt{36} = 6$
$frac{ sqrt{98} }{7} = frac{7 sqrt{2} }{7} = sqrt{2}$
$frac{ sqrt{648} }{18} = frac{18 sqrt{2} }{18} = sqrt{2}$
$frac{ sqrt{675} }{15} = frac{15 sqrt{3} }{15} = sqrt{3}$
$frac{875}{5} = frac{5 sqrt{35} }{5} = sqrt{35}$
$frac{ sqrt{216} }{6} = frac{6 sqrt{6} }{6 } = sqrt{6}$
$frac{ sqrt{486} }{9} = frac{9 sqrt{6} }{9} = sqrt{6}$
$frac{ sqrt{1280} }{16} = sqrt{80} = 4 sqrt{5}$
