Answer

To express the number `60,230,000,000,000,000,000,000` in standard form, we follow these steps:

### Step-by-Step Solution:

1. **Identify the significant digits**: The first step is to identify the significant digits in the number. Here, the significant digits are `6.023`.

2. **Count the number of places the decimal point is moved**: We need to move the decimal point in `6.023` to the right until we reach the original number. The original number is `60,230,000,000,000,000,000,000`, which has the decimal point at the end. Moving the decimal point from `6.023` to the end of the number involves counting how many places we move it:
- From `6.023` to `60.23` (1 place)
- From `60.23` to `602.3` (2 places)
- From `602.3` to `6023` (3 places)
- From `6023` to `60230` (4 places)
- From `60230` to `602300` (5 places)
- From `602300` to `6023000` (6 places)
- From `6023000` to `60230000` (7 places)
- From `60230000` to `602300000` (8 places)
- From `602300000` to `6023000000` (9 places)
- From `6023000000` to `60230000000` (10 places)
- From `60230000000` to `602300000000` (11 places)
- From `602300000000` to `6023000000000` (12 places)
- From `6023000000000` to `60230000000000` (13 places)
- From `60230000000000` to `602300000000000` (14 places)
- From `602300000000000` to `6023000000000000` (15 places)
- From `6023000000000000` to `60230000000000000` (16 places)
- From `60230000000000000` to `602300000000000000` (17 places)
- From `602300000000000000` to `6023000000000000000` (18 places)
- From `6023000000000000000` to `60230000000000000000` (19 places)
- From `60230000000000000000` to `602300000000000000000` (20 places)
- From `602300000000000000000` to `6023000000000000000000` (21 places)
- From `6023000000000000000000` to `60230000000000000000000` (22 places)

Thus, we moved the decimal point **22 places to the right**.

3. **Express in standard form**: In standard form, we express the number as:
\[ 6.023 \times 10^{22} \]

### Final Answer:
The number `60,230,000,000,000,000,000,000` in standard form is:
\[ 6.023 \times 10^{22} \]
