For this case we must find an expression equivalent to:
[tex]4,325,000,000[/tex]
To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:
[tex]4,325 * 10^{-9}[/tex]
If we run the decimal 9 spaces to the left we have:
[tex]0.000000004325[/tex]
Option B:
We discard it because the exponent is negative.
Option C:
[tex]4,325 * 10 ^ 6[/tex]
We run the decimal 6 spaces to the right
[tex]4,325,000[/tex]
Option D:
[tex]4,325 * 10 ^ 9[/tex]
We run the decimal 9 spaces to the right
[tex]4,325,000,000[/tex]
Answer:
Option D
