Answer
$6 \times 10^{7}$
Work Step by Step
Convert each number to scientific notation to find:
$=\dfrac{3 \times 10^{4}}{5 \times 10^{-4}}$
Divide the corresponding parts to find:
$=(3 \div 5) \times (10^{4} \div 10^{-4})
\\=0.6 \times 10^{4-(-4)}
\\=0.6 \times 10^{4+4}
\\=0.6 \times 10^{8}
\\=6 \times 10^{8-1}
\\=6 \times 10^{7}$
