Answer: 43/14
Step-by-step explanation: You take you 3 and times it by 14 and + 1 because the equation is saying 14/14 3 times plus the 1/14,
So 3 times 14=42
42+1=43 and then you take the 43 and put it over the 14 so now you have your answer: 43/14
Yes, I'm relatively sure any number can be written in scientific notation.
