Answer:
5.25 x 10^3
Step-by-step explanation:
To write 5250 into scientific notation, we need to move the decimal point as many places as neccesary to get a number between 0 and 10. Then, if we move the decimal place to the left we multiply by a power of 10 with a positive exponent and if we move the decimal place to the right, we multiply by a power of 10 with a negative exponent.
Therefore, 5250. is equivalent to:
5.25 x 10^3
Because we move the decimal point 3 places to the left.
