Describe what is menat by significant figure and order of magnitude

1.	Describe what is menat by significant figure and order of magnitude
Answer» tion:ORDER of magnitude states that if any digit is written in terms of power of 10 then the power of 10 digit will not be considered as SIGNIFICANT figureFor EXAMPLE: 2000m here total significant figures are FOUR but if we write this in terms of power of 10 then,it will be-2*10³m so here the significant figures will be only 1 bcoz of order of magnitude
