Answer 1

Extrae factores de:

$\sqrt{ \frac{450}{360} }$

$\sqrt{ \frac{5}{4} }$

$\frac{ \sqrt{5} }{2}$

************************

Extrae factores de:

$\sqrt{ \frac{900}{1200} }$

$\sqrt{ \frac{3}{4} }$

$\frac{ \sqrt{3} }{2}$

************************

Racionaliza:

$\frac{4}{3 \sqrt{5} }$

$\frac{4}{3 \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} }$

$\frac{4 \sqrt{5} }{3 \times 5}$

$\frac{4 \sqrt{5} }{15}$

************************

Racionaliza:

$\frac{2}{2 + \sqrt{2} }$

$\frac{2}{2 + \sqrt{2} } \times \frac{2 - \sqrt{2} }{2 - \sqrt{2} }$

$\frac{2(2 - \sqrt{2}) }{(2 + \sqrt{2}) \times (2 - \sqrt{2} ) }$

$\frac{2(2 - \sqrt{2} )}{4 - 2}$

$\frac{2(2 - \sqrt{2} )}{2}$

$2 - \sqrt{2}$
