Calculating the square root of 324 involves the following steps:

1. Recognize that \( \sqrt{324} \) asks for a number which, when multiplied by itself, equals 324.
2. Identify perfect squares close to 324, noting that \( 18 \times 18 = 324 \).
3. Therefore, \( \sqrt{324} = 18 \).

Square roots possess several important properties that contribute to their significance in mathematics:

1. Non-negative Result: \( \sqrt{x} \geq 0 \) for any non-negative number \( x \).
2. Multiplication: \( \sqrt{ab} = \sqrt{a} \cdot \sqrt{b} \) for non-negative numbers \( a \) and \( b \).
3. Addition and Subtraction: There are no simple formulas for \( \sqrt{a + b} \) or \( \sqrt{a - b} \) in general.
4. Inverse Relationship with Squaring: \( (\sqrt{x})^2 = x \).

Square roots find practical applications in various fields beyond mathematics:

• Engineering: Calculating dimensions and forces in structural designs.
• Physics: Determining velocities and accelerations in motion equations.
• Finance: Assessing risk and return in financial modeling.
• Computer Graphics: Scaling and transforming objects in digital imaging.
• Medicine: Analyzing waveforms in medical imaging technologies.
