How do you write 3,900 in scientific notation? _____ × 10^_____

Find Coefficient: Determine the coefficient for 3,900 in scientific notation. To find the coefficient, we need to move the decimal point to the left until we have a number between 1 and 10. Coefficient: 3.9Determine Sign: Decide whether 3,900 will have a positive or negative exponent in scientific notation. Since 3,900 is greater than 10, it will have a positive exponent.Calculate Exponent: Calculate the exponent for 3,900 in scientific notation. We moved the decimal point to the left 3 places to get the coefficient 3.9. 3,900 = 3.9 × 10^3 Exponent: 3Write in Scientific Notation: Write 3,900 in scientific notation using the coefficient and exponent. Substitute 3.9 for the coefficient and 3 for the exponent in the form a × 10^b. Scientific notation: 3.9 × 10^3
