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: $=(8.2 \cdot 3)\times (10^{7} \cdot 10^{9}) \\=24.6 \times 10^{7+9} \\=24.6 \times 10^{16} \\=2.46 \times 10^{17}$
