# Convert 251,000 to scientific notation.

$$2.51 \times 10^{5}$$

Explanation

To convert this number to scientific notation, move the decimal point to the left until it's to the immediate right of the first number, while counting the number of moves. In this case, you move it 5 places. The result is then multiplied by 10, raised to the power of the number of places the decimal point was moved.
