By scientific notation I am assuming you mean standard form, as that is used primarily in scientific calculations. The answer in standard form would be I hope this helps!
Scientific notation is when you move the decimal point to make it a number with decimal places times 10^xth power.
For this problem, the scientific notation would be:
4.954*10^-7.
4.954 is the number when you move the decimal 7 times. The number is "10^-7" because you move the decimal 7 times to the left to make the number smaller, rather than making it bigger.
