Question

(4.0 •10^6) divided by (5.0•10^9) in scientific notation

Answer 1

Answer:
`8.0*10^(-4)`

Explanation:

You need to remember the Quotient of powers property:

`(a^m)/(a^n)=a^((m-n))`

Then, given the expression:

`((4.0*10^6))/((5.0*10^9))`

You must divide the coefficients and subtract the exponents. Then:

`=0.8*10^(-3)`

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:

`=8.0*10^(-4)`
