Answer

a. $10^{3}$ b. $10^{5}$ c. $10^{-2}$ d. $10^{9}$

Work Step by Step

Estimate orders of magnitude. a. $2800 \approx 1 \times 10^{3}$ so the order of magnitude is $10^{3}$. b. $86.30 \times 10^{3} \approx 10 \times 10^{4}$ so the order of magnitude is $10^{5}$. c. $0.0076 \approx 10 \times 10^{-3}$ so the order of magnitude is $10^{-2}$. d. $15.0 \times 10^{8} \approx 1 \times 10^{9}$ so the order of magnitude is $10^{9}$.
