Final answer:
The value of the expression √x² is 5 for x = -5, 8 for x = -8, 0 for x = 0, 13 for x = 13, and 11 for x = 11.
Step-by-step explanation:
The expression √x² represents the square root of x squared. To evaluate this expression for different values of x, we substitute the given values into the expression.
- If x = -5, the expression becomes √(-5)² = √25 = 5.
- If x = -8, the expression becomes √(-8)² = √64 = 8.
- If x = 0, the expression becomes √0² = √0 = 0.
- If x = 13, the expression becomes √13² = √169 = 13.
- If x = 11, the expression becomes √11² = √121 = 11.
