Am nevoie urgent!!
$\sqrt{ \frac{18}{25} } + \sqrt{ \frac{32}{225 } } - \sqrt{ \frac{50}{9} }$
$\sqrt{ \frac{845}{576} } - \sqrt{ \frac{405}{36} } + \sqrt{ \frac{45}{4} }$
​

Answer 1

Răspuns:

1)

= 3√2/5  +  4√2/15  -  5√2/3  =  

= 9√2/15 + 4√2/15  -  25√2/15 =  

= - 12√2/15  =

= - 4√2/5

2)

= 13√5/24  -  9√5/6  +  3√5/2  =  

= 13√5//24  -  36√5/24  +  36√5/24 =

= 13√5/24
