The order of magnitude of `379` is

Options

A. `1`
B. `2`
C. `3`
D. `4`

Explanation

To find the order of magnitude of the number 379, follow these steps:

### Step 1: Express the number in scientific notation
To express 379 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.

For 379, we can write it as:
\[ 3.79 \times 10^2 \]

### Step 2: Identify the exponent
In the scientific notation \( 3.79 \times 10^2 \), the exponent of 10 is 2. This exponent indicates the order of magnitude of the number.

### Step 3: State the order of magnitude
The order of magnitude of the number 379 is therefore:
\[ \text{Order of magnitude} = 2 \]

### Final Answer
The order of magnitude of 379 is 2.
