Write the corresponding numeral for the following:`7xx100000000+6xx10000000+2xx1000000+8xx100000+5xx10000+3xx1000+2xx100+1xx10+4xx1`

Answer

To convert the expression `7xx100000000 + 6xx10000000 + 2xx1000000 + 8xx100000 + 5xx10000 + 3xx1000 + 2xx100 + 1xx10 + 4xx1` into a numeral, we will follow these steps:

### Step-by-Step Solution:

1. **Identify Each Term**:
- The expression consists of terms that represent different place values. Each term is a multiplication of a digit and a power of ten.

2. **Calculate Each Term**:
- \( 7 \times 100000000 = 700000000 \)
- \( 6 \times 10000000 = 60000000 \)
- \( 2 \times 1000000 = 2000000 \)
- \( 8 \times 100000 = 800000 \)
- \( 5 \times 10000 = 50000 \)
- \( 3 \times 1000 = 3000 \)
- \( 2 \times 100 = 200 \)
- \( 1 \times 10 = 10 \)
- \( 4 \times 1 = 4 \)

3. **Add All the Terms Together**:
- Now, we will sum all the calculated values:
\[ 700000000 + 60000000 + 2000000 + 800000 + 50000 + 3000 + 200 + 10 + 4 \]

4. **Perform the Addition**:
- Start adding from the largest value:
\[ 700000000 + 60000000 = 760000000 \]
\[ 760000000 + 2000000 = 762000000 \]
\[ 762000000 + 800000 = 762800000 \]
\[ 762800000 + 50000 = 762850000 \]
\[ 762850000 + 3000 = 762853000 \]
\[ 762853000 + 200 = 762853200 \]
\[ 762853200 + 10 = 762853210 \]
\[ 762853210 + 4 = 762853214 \]

5. **Final Result**:
- The final numeral representation of the expression is **762853214**.
