The number `sqrt0.0001` is:

Options

A. a rational number less the 0.01.
B. a rational number
C. an irrational number
D. neither a rational number nor an irrational number

Answer

To solve the question "The number √0.0001", we will follow these steps:

### Step 1: Rewrite the number in a simpler form
We start with the expression:
\[ \sqrt{0.0001} \]
We can express 0.0001 in scientific notation:
\[ 0.0001 = 1 \times 10^{-4} \]

### Step 2: Apply the square root to the scientific notation
Now we apply the square root to the expression:
\[ \sqrt{0.0001} = \sqrt{1 \times 10^{-4}} = \sqrt{1} \times \sqrt{10^{-4}} \]

### Step 3: Calculate the square roots
We know that:
\[ \sqrt{1} = 1 \]
And for the second part:
\[ \sqrt{10^{-4}} = 10^{-2} = \frac{1}{100} = 0.01 \]

### Step 4: Combine the results
Now we combine the results from Step 2:
\[ \sqrt{0.0001} = 1 \times 0.01 = 0.01 \]

### Final Answer
Thus, the value of \(\sqrt{0.0001}\) is:
\[ \sqrt{0.0001} = 0.01 \]
