OpenStudy (mathstudent55):
\( (3.8 \times 10^8)(6.9 \times 10^5)\)
\(= (3.8 \times 6.9) \times (10^8 \times 10^5)\)
\(= 26.22 \times 10^{8 + 5} \)
\(= 26.22 \times 10^{13}\)
The number above is the correct product, but it is not in scientific notation.
\(= 2.622 \times 10^{14} \)
Now it is correct and in scientific notation.
