neglect the resistances like 2,1,10 of side branches because they do not form a close loop between the points A and B , and also neglect the resistances like 1.8 and 2.2 because current doesn't traverse same path so further 3 and 1 resistances are in series i.e. equivalent 4 and finally resistances 4,4,2 are parallel so equivalent resistance 1 and finally 2,1 and 5 ohm resistors are in series so net equivalent resistance will be 8 ohm.
