Bonjour,

 \sqrt{128} =8 \sqrt{2}
 \sqrt{126} =3 \sqrt{14}
 \sqrt{550} =5 \sqrt{22}
 \sqrt{3 ^{3}*10^{5} } ≈1643,1..
 \sqrt{120} =2 \sqrt{30}
 \sqrt{0,08} = \frac{ \sqrt{2} }{5}
 \sqrt{0,75} = \frac{ \sqrt{3} }{2}
 \frac{ \sqrt{24} }{3} =2 \sqrt{2}
 \frac{ \sqrt{180} }{81} = \frac{2 \sqrt{5} }{3}
7 \sqrt{125} =35 \sqrt{5}
2 \sqrt{500} =20 \sqrt{5}

Voilà
