Write 0.000623 cm in a scientific notation.

Answer

To convert the number 0.000623 cm into scientific notation, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Number**: We start with the number 0.000623.

2. **Move the Decimal Point**: To express this number in scientific notation, we need to move the decimal point to the right until we have a number between 1 and 10. In this case, we move the decimal point 4 places to the right:
- 0.000623 → 6.23

3. **Count the Shift**: Since we moved the decimal point 4 places to the right, we need to account for this shift in our exponent. Moving the decimal to the right means we will use a negative exponent:
- The exponent will be -4.

4. **Write in Scientific Notation**: Now we can express the number in scientific notation format, which is \( N \times 10^x \):
- Therefore, 0.000623 cm can be written as:
\[ 6.23 \times 10^{-4} \text{ cm} \]

### Final Answer:
0.000623 cm in scientific notation is \( 6.23 \times 10^{-4} \text{ cm} \).
