Answer:
[tex]1.5\times10^{-3}[/tex]Explanation:
Given the rational expression
[tex]\frac{4.5\times10^3}{3\times10^6}[/tex]We can rewrite the fraction as:
[tex]=\frac{4.5}{3}\times\frac{10^3}{10^6}[/tex]We then simplify and apply the division law of indices to obtain:
[tex]\begin{gathered} =1.5\times10^{3-6} \\ =1.5\times10^{-3} \end{gathered}[/tex]Note: When you have the same base of an exponent and the terms are being divided, we simply subtract the power of the numerator from that of the denominator.
