Answer

$5 \times 10^{3}$

Work Step by Step

Divide the corresponding parts. Then, put the expression in the form $a*10^n$, where a is a number that is greater than or equal to 1 but less than 10. $=\dfrac{2.4}{4.8} \times \dfrac{10^{-2}}{10^{-6}} \\=0.5 \times 10^{-2-(-6)} \\=0.5 \times 10^{-2+6} \\=0.5 \times 10^{4} \\=5 \times 10^{4-1} \\=5 \times 10^{3}$
