Explicație pas cu pas:
[tex] \sqrt{ \frac{9}{4} } + \sqrt{ \frac{4}{9} } + \sqrt{ \frac{256}{81} } = [/tex]
[tex] \sqrt{9} = 3 \\ \sqrt{4} = 2 \\ \sqrt{256} = 16 \\ \sqrt{81} = 9[/tex]
[tex] \frac{3}{2} + \frac{2}{3} + \frac{16}{9} = \frac{3}{2} + \frac{2}{3} + \frac{16}{9} =[/tex]
Aducem totul la numitor comun
[tex] \frac{27+12+32}{18} = \frac{71}{18} [/tex]
