Answer:
[tex]3.015*10^{-7}[/tex].
Step-by-step explanation:
Given : 0.0000003105 .
To find : Write in scientific notation.
Solution : We have given 0.0000003105.
Steps to write in scientific notation :
Step 1 : If a number has n digit we move decimal point ( n-1) place to left
and to balance , multiply by [tex]10^{n-1}[/tex] .
We can write 0.0000003105 as [tex]\frac{3105}{10000000000}[/tex].
Or [tex]\frac{3105}{10^{10}}[/tex].
[tex]\frac{3.015*10^{3}}{10^{10} }[/tex].
[tex]\frac{3.015}{10^{7} }[/tex].
[tex]3.015*10^{-7}[/tex].
Therefore, [tex]3.015*10^{-7}[/tex].
