Okay, Placide, let's solve this one step by step. 8) Find the value of x if x² = 169 Step 1: Identify the equation. We are given the equation: x² = 169 Step 2: Take the square root of both sides to solve for x. When taking the square root of both sides of an equation, remember to include both the positive and negative roots. √(x²) = ±√(169) Step 3: Calculate the square root. The square root of 169 is 13. x = ± 13; The values of x are x = 13 or x = −13.

Okay, Placide, let's solve this one step by step.

8) Find the value of $x$ if $x^{2} = 169$

Identify the equation.
We are given the equation:
$x^{2} = 169$
Take the square root of both sides to solve for $x$ .
When taking the square root of both sides of an equation, remember to include both the positive and negative roots.
$\sqrt{x^{2}} = \pm\sqrt{169}$
Calculate the square root.
The square root of 169 is 13.
$x = \pm 13$
The values of $x$ are $\boxed{x = 13 \text{ or } x = -13}$ .
