Which of the following is the correct representation of 0.001 in scientific notation? (2023)

Step 1: Understand that scientific notation is a way to express numbers as a product of a number between 1 and 10 and a power of 10.
Step 2: Identify the number you want to convert, which is 0.001.
Step 3: Move the decimal point in 0.001 to the right until you have a number between 1 and 10. In this case, move it 3 places to the right to get 1.
Step 4: Count how many places you moved the decimal point. Since you moved it 3 places to the right, this will be represented as a negative exponent.
Step 5: Write the number you found (1) and multiply it by 10 raised to the power of -3. This gives you 1 x 10^-3.
Step 6: Therefore, the scientific notation for 0.001 is 1 x 10^-3.
