Urgent! Va rog! Dau coroana ​

Answer 1

Răspuns:

Explicație pas cu pas:

6,(1) = (61-6)9 = 55/9

55/(55/9) = 9

6,(2) = 56/9

56/(56/9) = 9

x =V9 +V9+...+V9 =

3+3+3+...+3 = 8*3 = 24

Answer 2

$\sqrt{\frac{55}{\frac{6*9+1}{9} } } +\sqrt{\frac{56}{\frac{6*9+2}{9} } } +...+\sqrt{\frac{62}{\frac{6*9+8}{9} } }$=

$\sqrt{55*\frac{9}{55} } +\sqrt{56*\frac{9}{56} }+...+\sqrt{62*\frac{9}{62} } =$

$\sqrt{9}+\sqrt{9}+\sqrt{9} +...+\sqrt{9} =3*8=24$
