$\frac{5 \times 10^{8}}{2 \times 10^{15}} = 2.5 \times 10^{- 7}$ $(5xx10^8)/(2xx10^15)=2.5xx10^(-7)$

$\frac{5 \times 10^{8}}{2 \times 10^{15}}$ $(5xx10^8)/(2xx10^15)$

= $\frac{5}{2} \times \frac{10^{8}}{10^{15}}$ $5/2xx10^8/10^15$

Now using $\frac{a^{m}}{a^{n}} = a^{m - n}$ $a^m/a^n=a^(m-n)$ , above can be reduced to

= $\frac{5}{2} \times 10^{8 - 15}$ $5/2xx10^(8-15)$

= $2.5 \times 10^{- 7}$ $2.5xx10^(-7)$
