A. \(0.5 \times 10^{-3} = 0.0005\) NO
B. \(5
C. \(\frac{0.05 }{ 10^{-6}} = 0.05 * 10^{6} = 50000\) NO
D. \(5 \times 10^3 = 5000\) NO
E. \(\frac{10^{-5}}{10^{-7}} = 10^2 = 100\) YES

Solution:
We are asked which of the options fall under the range: 5 and 5000.
let us analyze each option individually:
Option A: \(0.5 * 10^{-3}\)
\(⇒ \frac{5}{10} * 10^{-3}\)
\(⇒ 5 *10^{-4}\)
This does not lie in the range.
Option B: \(50000(0.00005)\)
\(⇒ 50000*\frac{5}{100000}\)
\(⇒ 2.5 \)
This does not lie in the range.
Option C: \(\frac{0.05}{10^{-6}}\)
\(⇒ \frac{5}{100*10^{-6}}\)
\(⇒ 50000\)
This does not lie in the range.
Option D: \(5*10^3\)
\(⇒ 5000\)
This does not lie in the range.
Option E: \(\frac{10^{-5}}{10^{-7}}\)
\(⇒ 10^{-5+(-7)}\)
\(⇒ 10^2\)
\(⇒ 100\)
This lies in the range.
Hence the right answer is Option E
