## Understanding (9y)^2 Without Parentheses

In mathematics, parentheses are used to indicate the order of operations. When we see an expression like **(9y)^2**, it means we need to square the entire quantity inside the parentheses, which is 9y.

### Expanding the Expression

To understand what this means without the parentheses, we can expand the expression:

**(9y)^2 = (9y) * (9y)**

This tells us that we are multiplying 9y by itself.

### Applying the Distributive Property

To simplify further, we can apply the distributive property of multiplication:

**(9y) * (9y) = (9 * 9) * (y * y)**

This gives us:

**81y^2**

### Conclusion

Therefore, **(9y)^2** without parentheses is simply **81y^2**. It is important to understand how parentheses affect the order of operations to correctly simplify expressions.
