Printable worksheet designed to help students practice multiplying various integers by the power of 1,000.

Let's solve the worksheet titled "Multiply by powers of 10". In this case, all problems involve multiplying numbers by 1,000, which is a power of 10 (specifically, $10^3$).

🔍 Key Concept:

When you multiply a number by 1,000, you add three zeros to the end of the number (or move the decimal point three places to the right, if there were decimals). Since all these numbers are whole numbers, we simply add three zeros.

💡 Explanation:

Multiplying by 1,000 increases the value of a number by three place values. So:
- Each digit shifts three places to the left.
- You just append three zeros at the end.

For example:
$ 39 \to 39,000 $ — because 39 becomes 39 thousand.

This concept is fundamental in understanding place value and powers of 10.

✔ All answers are correct and follow this simple rule!
