Calculate the Square Root of 169: Basic Radical Evaluation

To solve for the square root of 169, we need to determine which whole number, when multiplied by itself, equals 169.

• Step 1: Recall that squaring a number means multiplying the number by itself. Therefore, we need to find a number $n$ such that $n \times n = 169$.
• Step 2: Check known square values or perform some calculations: $13 \times 13 = 169$.
• Step 3: Verify that $13^2 = 169$, confirming that 13 is the square root.

Therefore, the solution to the problem is $\sqrt{169} = 13$.
