Final answer:
To write 92,420 in scientific notation, move the decimal point four places to the left, resulting in 9.2420 x 10^4.
Step-by-step explanation:
To write the number 92,420 in scientific notation, we need to move the decimal point to the right until there is only one digit to the left of the decimal point. Count the number of decimal places you moved the decimal point. If you move it to the right, the exponent will be negative. If you move it to the left, the exponent will be positive. In this case, the decimal point needs to move four places to the left, resulting in the number 9.2420. To compensate for moving the decimal point, the exponent of 10 will be positive 4, so the scientific notation for 92,420 is 9.2420 x 10^4.
