QuestionCalculate $8.12 \times 10^{6} \times 4.7 \times 10^{3}$ using scientific notation. Give your answer with correct significant figures.

Studdy Solution
Finally, we need to express our answer with the proper number of significant figures. Both of our original numbers had three significant figures, so our final answer should also have three significant figures. We round3.8164 to3.82 (since the digit after1 is6 which is greater than5, so we round up).
$$3.8164 \times10^{11} =3.82 \times10^{11}$$So, $.12 \times10^{6}$ times $4.7 \times10^{3}$ equals $3.82 \times10^{11}$ in scientific notation with the proper number of significant figures.
