What is ` 4,563,021, div 10^(5)`, rounded to the nearest whole number?

Answer

To solve the problem of finding `4,563,021 div 10^(5)` rounded to the nearest whole number, we will follow these steps:

### Step 1: Understand the expression
We need to divide `4,563,021` by `10^5`. The expression `10^5` means `10` raised to the power of `5`, which equals `100,000`.

### Step 2: Perform the division
Now, we divide `4,563,021` by `100,000`:

\[ 4,563,021 \div 100,000 = 45.63021 \]

### Step 3: Round to the nearest whole number
Next, we need to round `45.63021` to the nearest whole number. To do this, we look at the digit in the tenths place, which is the first digit after the decimal point.

In `45.63021`, the tenths place is `6`.

### Step 4: Apply rounding rules
According to rounding rules:
- If the digit in the tenths place is 5 or greater, we round up.
- If the digit is less than 5, we round down.

Since `6` is greater than `5`, we round up `45` to `46`.

### Final Answer
Thus, `4,563,021 div 10^(5)` rounded to the nearest whole number is **46**.
