Solve: 6×100,000 + 4×10,000 + 2×1,000 + 7 Expanded Form Equation

To solve this problem, we'll follow these steps:

• Step 1: Perform the individual multiplications in the expression.
• Step 2: Add the results of these multiplications.

Now, let's work through each step:
Step 1: Compute each multiplication term:
- $6 \times 100,000 = 600,000$
- $4 \times 10,000 = 40,000$
- $2 \times 1,000 = 2,000$
- $7 \times 1 = 7$

Step 2: Sum the results from Step 1:
$600,000 + 40,000 + 2,000 + 7 = 642,007$

Therefore, the solution to the equation is $642,007$.
