### Q: What are some properties of perfect squares?

Perfect squares have a units digit of 0, 1, 4, 5, 6, or 9. The units digit of the square determines the units digit of its square root.

### Q: How can we trust that all perfect squares have these properties?

By observing the squares of the first 10 natural numbers and larger numbers, we can see that all perfect squares indeed follow the pattern of having a units digit of 0, 1, 4, 5, 6, or 9.

### Q: How can the units place of a perfect square be determined?

When multiplying two numbers to find the square, the units place of the result is obtained by multiplying the units places of the original numbers. This applies to perfect squares as well.

### Q: What is the significance of the units digit in a perfect square?

The units digit in a perfect square determines the units digit of the result when the square is calculated. This digit will be 0, 1, 4, 5, 6, or 9.

## Summary & Key Takeaways

• Numbers that end in 0, 1, 4, 5, 6, or 9 are perfect squares.

• The units place of a perfect square determines the units place of its square root.

• Squaring any number always results in a perfect square with a units digit of 0, 1, 4, 5, 6, or 9.
