Answer 2

$R_1=R_2=R_3=R_4=R_5 = x\\R_{1,2}=R_1+R_2=x+x=2x\\R_{1,2,3}=\frac{R_{1,2}*R_{3}}{R_{1,2}+R_{3}} =\frac{2x*x}{2x+x}=\frac{2x}{3} \\R_{1,2,3,4}=R_{1,2,3}+R_{4} =\frac{2x}{3}+x=\frac{5}{3} x=1\frac{2}{3}x \\R_{1,2,3,4,5}=\frac{R_{1,2,3,4}*R_{5}}{R_{1,2,3,4}+R_{5}} =\frac{1\frac{2}{3}x*x}{1\frac{2}{3}x+x} =\frac{5x}{8}$

Rзаг = 5 Om

$\frac{5x}{8} =5Om\\\frac{8}{5} *\frac{5x}{8} =\frac{8}{5} *5\\x=8 Om$

$R_1=R_2=R_3=R_4=R_5 = 8Om$
