Answer
$2.46 \times 10^{17}$
Work Step by Step
Convert each number to scientific notation to find:
$=(8.2 \times 10^{7})(3 \times 10^9)$
Multiply the corresponding parts together to find:
$=(8.2 \cdot 3)\times (10^{7} \cdot 10^{9})
\\=24.6 \times 10^{7+9}
\\=24.6 \times 10^{16}
\\=2.46 \times 10^{17}$
