Answer:
C) [tex]8.47\times 10^{-5}[/tex]
Step-by-step explanation:
The given number is [tex]0.0000847[/tex]
The scientific notation is when we write the number in the form [tex]k\times 10^n[/tex] where [tex]1\le k\le 10[/tex] and n is an integer.
We need to move the decimal point forward to get [tex]0.0000847[/tex] to this form.
[tex]0.0000847=8.47\times 10^{-5}[/tex]
The correct choice is C.
