Verified step by step guidance1
Identify the expression to evaluate: the square root of 144, written as \(\sqrt{144}\).
Recall that the square root of a number is a value that, when multiplied by itself, gives the original number.
Recognize that 144 is a perfect square because it can be expressed as \(12 \times 12\).
Therefore, rewrite the square root as \(\sqrt{12 \times 12}\) to see the relationship clearly.
Use the property of square roots that \(\sqrt{a \times a} = a\) to simplify \(\sqrt{12 \times 12}\) to 12.
