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.

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

### Step 2: Identify the order of magnitude
The order of magnitude is determined by the power of 10 in the scientific notation. In this case, the power of 10 is \(-3\).

### Step 3: Express in a suitable form
Since the order of magnitude is typically expressed with one digit left to the decimal point, we can also express \(7.01 \times 10^{-3}\) as:
\[ 0.701 \times 10^{-2} \]
However, the power of 10 that represents the order of magnitude remains \(-2\) since we are looking for the least way of representation.

### Conclusion
Thus, the order of magnitude of \(0.00701\) is \(-2\).

### Final Answer
The order of magnitude of \(0.00701\) is \(-2\).
