Question

Solve 1/2R+1/2R+1/R=?​

Answer 1

$\huge\boxed{\underline{\bf { \red S \green O \pink L \blue U \orange T \purple I \red O \pink N \green{..}}}}$

$\longmapsto \sf \frac{1}{2R} + \frac{1}{2R} + \frac{1}{R}$

$\longmapsto \sf \frac{1 + 1 + 2}{2R}$

$\longmapsto \sf \frac{4}{2R}$

$\longmapsto \sf \frac{2}{R}$
