Fill in the blanks:
`65xx8156g=_________g=_______mg`

Answer

To solve the problem, we need to fill in the blanks for the expression `65xx8156g=_________g=_______mg`. We will follow these steps:

### Step 1: Multiply 65 by 8156
We start by multiplying the two numbers together.

1. **Multiply 65 by 8156**:
- Break down the multiplication:
- \( 65 \times 8156 \)
- We can do this step by step:
- \( 65 \times 6 = 390 \)
- \( 65 \times 50 = 3250 \) (since \( 50 = 5 \times 10 \))
- \( 65 \times 100 = 6500 \)
- \( 65 \times 8000 = 520000 \)
- Now, add these results together:
- \( 390 + 3250 + 6500 + 520000 = 530140 \)

So, \( 65 \times 8156 = 530140 \) grams.

### Step 2: Convert grams to milligrams
Next, we need to convert the result from grams to milligrams.

2. **Convert grams to milligrams**:
- We know that \( 1 \text{ gram} = 1000 \text{ milligrams} \).
- Therefore, to convert 530140 grams to milligrams:
- \( 530140 \text{ grams} \times 1000 = 530140000 \text{ milligrams} \)

### Final Answers
Now we can fill in the blanks:
- \( 65 \times 8156 \text{ grams} = 530140 \text{ grams} \)
- \( 530140 \text{ grams} = 530140000 \text{ milligrams} \)

So the final answer is:
- `65xx8156g=530140g=530140000mg`
