The length of one rod is `2.53 cm` and that of the other is `1.27 cm`. The least count of the measuring instrument is `0.01 cm`. If the two rods are put together end to end , find the combined length.

The length of one rod l_(1)=3.323cm and the other is l_(2)=3.321cm both rods were measured with one measuring instrument with least count 0.001 cm Then (l_(1)-l_(2)) is
