## Understanding (5u)^2

In mathematics, **(5u)^2** represents the square of the expression **5u**. Let's break down how to solve this.

### Understanding the Concepts

**Exponent:**The exponent "2" indicates that we are multiplying the base (5u) by itself.**Base:**The base is the expression being multiplied by itself, which is**5u**in this case.

### Solving (5u)^2

To solve this, we need to apply the exponent rule:
**(ab)^n = a^n * b^n**

**Apply the rule:**(5u)^2 = 5^2 * u^2**Simplify:**5^2 * u^2 =**25u^2**

### Conclusion

Therefore, **(5u)^2** simplifies to **25u^2**. It's important to remember that the exponent applies to both the coefficient (5) and the variable (u).
