Answer:
5.21313 x 10⁴
Step-by-step explanation:
To write the number in scientific notation, we need to move the decimal place until getting a number between 0 and 10. In this case, we need to move the decimal point 2 places to the left, so
521.3130 x 10² is equivalent to:
![5.213130*10^2*10^2](https://img.qammunity.org/2023/formulas/physics/high-school/nb99rxon5rw2z2qns1hg4iook5ir9q8nrs.png)
Where we multiply by 10² because we move the decimal point 2 places to the left. Now, we can simplify the number to get:
![5.21313*10^4](https://img.qammunity.org/2023/formulas/physics/high-school/rtvciaz4e4qt74rqvyb3xcee7b2xkwrqyf.png)
Therefore, the answer is:
5.21313 x 10⁴
