Question I.5: Add 1.95 × 10^-2 and 2.8 × 10^-3.
Add 1.95 × 10^{-2}\ \text{and} \ 2.8 × 10^{-3}.
To add these two numbers, we make both exponents -2. Thus, 2.8 × 10^{-3} = 0.28 × 10^{-2}. Now we can add:
\hspace{10 pt} 1.95 \times 10^{-2} \\ \underline{+ \ 0.28 \times 10^{-2}} \\ \hspace{11 pt}2.23 \times 10^{-2}Related Answered Questions
