A question of orders of magnitude
Posted:
Nov 30, 2012 7:27 PM


I'm reading a book in which the author compares two pairs of numbers (0.31, 0.39) and (6.10,0.39) and multiplies the second member of each pair by a factor R_1 = 2 and R_2 = 20 so that both members of the pair "have the same order of magnitude". Subsequently the pairs of numbers become (0.31, 2 x 0.39) and (6.10 , 20 x 0.39). I'd appreciate help in understand how these numbers satisfy the stated condition.
