Question

URGENTT CALCULEAZA B​

Answer 1

Răspuns:

$b = 10 \times ( \frac{ \sqrt{50} }{50} + \frac{ \sqrt{5} }{10} - \frac{ \sqrt{20} }{20} )$

$b = 10 \times ( \frac{5 \sqrt{2} }{50} + \frac{ \sqrt{5} }{10} - \frac{2 \sqrt{5} }{20} )$

$b = 10 \times ( \frac{ \sqrt{2} }{10} + \frac{ \sqrt{5} }{10} - \frac{ \sqrt{5} }{10} )$

$b = \sqrt{2}$
