## Understanding (9w)^2 Without Parentheses

The expression **(9w)^2** represents the square of the entire quantity 9w. To understand what this means without parentheses, let's break it down:

**1. What is a square?**

Squaring a number means multiplying it by itself. For example, 5² = 5 * 5 = 25.

**2. Applying this to our expression**

In the case of (9w)², we're squaring the entire term 9w. This means:

(9w)² = (9w) * (9w)

**3. Expanding the multiplication**

To remove the parentheses, we simply multiply the terms within them.

(9w) * (9w) = 9 * w * 9 * w

**4. Simplifying the expression**

Rearranging the terms and combining the numerical values:

9 * 9 * w * w = **81w²**

**Therefore, (9w)² without parentheses is equivalent to 81w².**

**Key takeaway:** When squaring an expression within parentheses, we square each term inside the parentheses and then multiply the results.
