Answer:
\(3.015*10^{-7}\).
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 \(10^{n-1}\) .
We can write 0.0000003105 as \(\frac{3105}{10000000000}\).
Or \(\frac{3105}{10^{10}}\).
\(\frac{3.015*10^{3}}{10^{10} }\).
\(\frac{3.015}{10^{7} }\).
\(3.015*10^{-7}\).
Therefore, \(3.015*10^{-7}\).
