Convert the following octal numbers to binary:

(a) 123

(b) 3527

(c) 705

(a) 123

Therefore, (123)₈ = ($\bold{\underlinesegment{001}}\medspace\bold{\underlinesegment{010}}\medspace\bold{\underlinesegment{011}}$)₂

(b) 3527

Therefore, (3527)₈ = ($\bold{\underlinesegment{011}}\medspace\bold{\underlinesegment{101}}\medspace\bold{\underlinesegment{010}}\medspace\bold{\underlinesegment{111}}$)₂

(c) 705

Therefore, (705)₈ = ($\bold{\underlinesegment{111}}\medspace\bold{\underlinesegment{000}}\medspace\bold{\underlinesegment{101}}$)₂
