It looks like you've uploaded a worksheet titled
"Standard Form - Practice the Skill" that contains 10 problems asking to write numbers in
standard form (also known as
scientific notation). However, I cannot see the actual image or its content because it's not displayed here.
To help you solve this, I’ll explain how to convert numbers into
standard form and provide examples based on typical problems found on such worksheets. If you can describe the specific numbers or list them, I can solve them directly.

🔢 What is Standard Form?
Standard form (scientific notation) expresses a number as:
>
a × 10ⁿ
Where:
-
a is a number between 1 and 10 (inclusive of 1, exclusive of 10),
-
n is an integer (positive or negative).
---
✔ Steps to Convert to Standard Form:
1. Move the decimal point so that only
one non-zero digit is to the left of the decimal.
2. Count how many places you moved the decimal.
- If you moved it
left, the exponent is
positive.
- If you moved it
right, the exponent is
negative.
3. Write the number as:
a × 10ⁿ

🧩 Example Problems (Typical from This Worksheet)
Let’s assume your worksheet includes numbers like these. Here are common ones and their solutions:
| Problem | Standard Form |
|--------|----------------|
| 1. 6 billion | 6 × 10⁹ |
| 2. 75 million | 7.5 × 10⁷ |
| 3. 850,000 | 8.5 × 10⁵ |
| 4. 0.00045 | 4.5 × 10⁻⁴ |
| 5. 9,000,000,000 | 9 × 10⁹ |
| 6. 0.0000007 | 7 × 10⁻⁷ |
| 7. 340,000 | 3.4 × 10⁵ |
| 8. 0.00000000012 | 1.2 × 10⁻¹⁰ |
| 9. 45,000,000 | 4.5 × 10⁷ |
| 10. 0.000000000008 | 8 × 10⁻¹² |

💡 Tips:
- "Billion" = 10⁹
- "Million" = 10⁶
- "Thousand" = 10³
- For decimals: count zeros after the decimal before the first non-zero digit.
