Q. How do you write 570 in scientific notation?_____×10_____
Identify significant digit: Identify the most significant digit in the number 570. The most significant digit is 5 because it is the first non-zero digit from the left.
Place decimal point: Place the decimal point after the most significant digit to create a number between 1 and 10. By placing the decimal after the 5, we get 5.70, which is between 1 and 10.
Count decimal point moves: Count the number of places the decimal point has been moved to get from the original number to the new number between 1 and 10. The decimal point in 570 is after the last zero, so it has been moved two places to the left to get 5.70.
Write as product: Write the number as a product of the number obtained in Step 2 and 10 raised to the power of the number of places the decimal point was moved.Since the decimal point was moved two places, we write 570 as 5.70×102.
