b) - radical 6 / 8 + 5 radical 6 / 12 - 2 radical 6 / 3
plz​

Answer 1

Explicație pas cu pas:

Salutare! ¯\_(ツ)_/¯

$a) \frac{ \sqrt{2} }{3} + \frac{3 \sqrt{2} }{4} - \frac{5 \sqrt{2} }{7}$

$\frac{28 \sqrt{2} }{84} + \frac{63 \sqrt{2} }{ 84 } - \frac{60 \sqrt{2} }{84}$

$\frac{31 \sqrt{2} }{84}$

$b) - \frac{ \sqrt{6} }{8} + \frac{5 \sqrt{6} }{12} - \frac{2 \sqrt{6} }{3}$

$- \frac{3 \sqrt{6} }{24} + \frac{10 \sqrt{6} }{24} - \frac{16 \sqrt{6} }{24}$

$\frac{ - 9 \sqrt{6} }{24} = - \frac{3 \sqrt{6} }{8}$
