Step-by-step explanation:
[tex] \\ \sf \frac{3 \times {10}^{ - 3} }{6 \times {10}^{ - 7} } [/tex]
[tex] \\ \sf = \frac{1}{2} \times {10}^{ - 3 - ( - 7)} [/tex]
[tex] \\ \sf = \frac{1}{2} \times {10}^{4} [/tex]
[tex] \\ \sf = 0.5 \times {10}^{ 1} \times {10}^{3} [/tex]
[tex] \\ \sf = 5 \times {10}^{3} [/tex]
[tex] \\ \sf = 5000[/tex]
