The order of magnitude of `0.00701` is

Options

A. `-2`
B. `-1`
C. `2`
D. `1`

Explanation

To find the order of magnitude of the number \(0.00701\), we can follow these steps:

### Step 1: Convert the number to scientific notation
To express \(0.00701\) in scientific notation, we need to move the decimal point to the right until we have a number between \(1\) and \(10\).

- Moving the decimal point two places to the right gives us:
\[ 0.00701 = 7.01 \times 10^{-3} \]

### Step 2: Identify the exponent
In scientific notation, the exponent indicates the order of magnitude. Here, the exponent is \(-3\).

### Step 3: Determine the order of magnitude
The order of magnitude is defined as the power of ten when the number is expressed in scientific notation. Since we have:
\[ 0.00701 = 7.01 \times 10^{-3} \]
The order of magnitude of \(0.00701\) is \(-3\).

### Final Answer
Thus, the order of magnitude of \(0.00701\) is \(-3\).
