Answer

$5.64 \times 10^{17}$

Work Step by Step

Convert each number to scientific notation to find: $=(9.4 \times 10^{7})(6 \times 10^{9})$ Multiply the corresponding parts together to find: $=(9.4 \cdot 6)\times (10^{7} \cdot 10^{9}) \\=56.4 \times 10^{7+9} \\=56.4 \times 10^{16} \\=5.64 \times 10^{16+1} \\=5.64 \times 10^{17}$
