Answer: [tex]8.0*10^{-4}[/tex]
Step-by-step explanation:
You need to remember the Quotient of powers property:
[tex]\frac{a^m}{a^n}=a^{(m-n)}[/tex]
Then, given the expression:
[tex]\frac{(4.0*10^6)}{(5.0*10^9)}[/tex]
You must divide the coefficients and subtract the exponents. Then:
[tex]=0.8*10^{-3}[/tex]
In order to write this result in Scientific notation form, you need to move the decimal point one place to the right. Therefore, you get:
[tex]=8.0*10^{-4}[/tex]
