Essential University Physics: Volume 1 (3rd Edition)

Recall, numbers with negative exponents in scientific notation are small while numbers with large exponents are large. Thus, in terms of size: $2,998\times 10^{-9}, .0008, 3.14 \times 10^7, .041 \times 10^9, 55 \times 10^6$ In terms of significant figures: $.0008 = .041\times 10^9 = 55 \times 10^6 < 3.14 \times 10^7 < 2.998 \times 10^{-9}$
