Give the order of the following :
499

Answer

To determine the order of magnitude of the number 499, we can follow these steps:

### Step 1: Identify the number
The number given is 499.

### Step 2: Express the number in scientific notation
To express 499 in scientific notation, we need to write it in the form of \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.

We can write:
\[ 499 = 4.99 \times 10^2 \]
Here, we have moved the decimal point two places to the left.

### Step 3: Determine the exponent
In the scientific notation \( 4.99 \times 10^2 \), the exponent is 2.

### Step 4: Consider the value of \( a \)
Since the coefficient \( 4.99 \) is less than 5, we do not need to adjust the exponent.

### Step 5: Conclusion
Thus, the order of magnitude of 499 is:
\[ \text{Order of magnitude} = 2 \]

### Summary
The order of the number 499 is 2.
