Write the number whose expanded form is given below:
`4xx10,00,000+2xx1,00,000+3xx10,000+7xx10+1`

Answer

To find the number whose expanded form is given, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Expanded Form**: The expanded form provided is:
\[ 4 \times 10,00,000 + 2 \times 1,00,000 + 3 \times 10,000 + 7 \times 10 + 1 \]

2. **Calculate Each Term**:
- For \(4 \times 10,00,000\):
\[ 4 \times 10,00,000 = 40,00,000 \]
- For \(2 \times 1,00,000\):
\[ 2 \times 1,00,000 = 2,00,000 \]
- For \(3 \times 10,000\):
\[ 3 \times 10,000 = 30,000 \]
- For \(7 \times 10\):
\[ 7 \times 10 = 70 \]
- For \(1\):
\[ 1 = 1 \]

3. **Add All the Calculated Values**:
Now we will add all these values together:
\[ 40,00,000 + 2,00,000 + 30,000 + 70 + 1 \]

4. **Perform the Addition**:
- Start from the rightmost side:
- \(0 + 0 + 0 + 0 + 1 = 1\)
- \(0 + 0 + 0 + 7 + 0 = 7\)
- \(0 + 0 + 3 + 0 + 0 = 3\)
- \(0 + 2 + 0 + 0 + 0 = 2\)
- \(4 + 0 + 0 + 0 + 0 = 4\)

5. **Combine the Results**:
Putting it all together, we get:
\[ 42,30,071 \]

### Final Answer:
The number whose expanded form is given is **42,30,071**.
