1.	What is the difference between the following ? (i)2.5xx10^(3)g and 2.50 xx10^(3)g (ii) 160 cm and 160.0 cm.
Answer» Solution :(i) `2.5xx10^(3)` has two SIGNIFICANT FIGURES while `2.50xx10^(3)` has three significant figures. Hence, `2.50xx10^(3)` represents GREATER accuracy than `2.5xx10^(3)` . (II) 160 has three significant figures while 160.0 has four significant figures. Hence, 160.0 represents greater accuracy.
