## Understanding (8u)^2 without parentheses

The expression (8u)^2 represents the square of the entire term **8u**. This means that both the coefficient **8** and the variable **u** are being squared.

Here's a breakdown:

**1. Expanding the Expression:**

**(8u)^2 = 8u * 8u**

**2. Applying the Exponent Rule:**

**8u * 8u = 8 * 8 * u * u**

**3. Simplifying the Expression:**

**8 * 8 * u * u = 64u^2**

Therefore, (8u)^2 without parentheses is **64u^2**.

**Key Takeaways:**

**Exponent rules apply to the entire term within parentheses.****Squaring a term involves multiplying it by itself.****The coefficient and variable are both squared when the entire term is squared.**
