Estimate each of the following products by rounding off each number to the nearest ten :
`38xx63`

Answer

To estimate the product of 38 and 63 by rounding each number to the nearest ten, we can follow these steps:

### Step 1: Round 38 to the nearest ten.
- Look at the digit in the ones place of 38, which is 8.
- Since 8 is greater than 5, we round up.
- Add 1 to the digit in the tens place (3), which gives us 4.
- Replace the ones place with 0.
- Therefore, 38 rounded to the nearest ten is **40**.

### Step 2: Round 63 to the nearest ten.
- Look at the digit in the ones place of 63, which is 3.
- Since 3 is less than 5, we round down.
- The digit in the tens place (6) remains the same.
- Replace the ones place with 0.
- Therefore, 63 rounded to the nearest ten is **60**.

### Step 3: Multiply the rounded numbers.
- Now, we multiply the rounded values: 40 and 60.
- Calculate:
- \( 40 \times 60 = 2400 \).

### Final Answer:
The estimated product of 38 and 63 is **2400**.
