Give the order of the following :
501

Answer

To find the order of magnitude of the number 501, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Number**: We are given the number 501.

2. **Express in Scientific Notation**: To express 501 in scientific notation, we need to write it in the form of \( a \times 10^n \), where \( 1 \leq a < 10 \).
- We can write 501 as \( 5.01 \times 10^2 \).

3. **Determine the Exponent**: The exponent \( n \) in the scientific notation \( 5.01 \times 10^2 \) is 2.

4. **Identify the Order of Magnitude**: The order of magnitude is defined as the exponent \( n \) when the number is expressed in scientific notation.
- Therefore, the order of magnitude of 501 is **2**.

### Final Answer:
The order of the number 501 is **2**.
