The exact form of the square root of 360 can be determined by simplifying it through prime factorization. This process breaks down 360 into its prime components, allowing us to simplify the square root in an exact form. Here's a detailed step-by-step explanation:

1. Prime Factorization:
   • 360 can be factorized into prime numbers as follows:
   • 360 = 2 × 180
   • 180 = 2 × 90
   • 90 = 2 × 45
   • 45 = 3 × 15
   • 15 = 3 × 5
   • Thus, 360 = 2³ × 3² × 5.
2. Pairing the Prime Factors:
   • To simplify the square root, we pair the prime factors:
   • \(\sqrt{360} = \sqrt{2^3 \times 3^2 \times 5}\)
   • Rewrite as: \(\sqrt{360} = \sqrt{(2^2 \times 2) \times (3^2) \times 5}\)
   • Simplify further: \(\sqrt{360} = \sqrt{2^2} \times \sqrt{3^2} \times \sqrt{2 \times 5}\)
3. Simplifying the Expression:
   • \(\sqrt{2^2} = 2\)
   • \(\sqrt{3^2} = 3\)
   • Therefore, \(\sqrt{360} = 2 \times 3 \times \sqrt{10}\)

   • For simplicity, use the approximation: \(\sqrt{360} \approx 18.97\).

The decimal value of the square root of 360 is approximately:

In many practical situations, rounding this value to two decimal places is sufficient, resulting in 18.97. This approximation is useful for quick calculations and provides a sufficient level of precision for most everyday uses.

Simplifying the square root of 360 involves breaking it down into its prime factors and finding perfect squares. Follow these steps to simplify:

1. First, find the prime factorization of 360:
   • 360 ÷ 2 = 180
   • 180 ÷ 2 = 90
   • 90 ÷ 2 = 45
   • 45 ÷ 3 = 15
   • 15 ÷ 3 = 5
   • 5 ÷ 5 = 1

   So, the prime factorization of 360 is \(2^3 \times 3^2 \times 5\).

2. Next, pair the prime factors to identify the perfect squares:
   • \(2^3\) can be written as \(2^2 \times 2\), where \(2^2\) is a perfect square.
   • \(3^2\) is already a perfect square.
   • \(5\) remains as it is.
3. Group the perfect squares:
   • \(\sqrt{2^2 \times 3^2 \times 2 \times 5} = \sqrt{2^2} \times \sqrt{3^2} \times \sqrt{2 \times 5}\)
4. Simplify the square roots of the perfect squares:
   • \(\sqrt{2^2} = 2\)
   • \(\sqrt{3^2} = 3\)

   So, \(\sqrt{2^2 \times 3^2 \times 2 \times 5} = 2 \times 3 \times \sqrt{10}\).

5. Finally, multiply the simplified terms:
   • \(2 \times 3 = 6\)
   • \(6 \times \sqrt{10}\)

   Therefore, the simplified form of \(\sqrt{360}\) is \(6\sqrt{10}\).

The square root of 360, approximately 18.97, has several interesting applications in various fields. Here are some examples of how it can be used:

• Geometry and Area Calculations:

  In geometry, square roots are often used to determine the dimensions of a square given its area. If a square has an area of 360 square units, the length of each side is the square root of 360, which is approximately 18.97 units.

• Physics and Gravity:

  Square roots are used in physics, particularly in equations involving gravity. For instance, the time \( t \) (in seconds) it takes for an object to fall from a height \( h \) (in feet) can be determined using the formula \( t = \frac{\sqrt{h}}{4} \). If an object is dropped from a height of 360 feet, the time it takes to reach the ground is \( \frac{\sqrt{360}}{4} \), which is approximately 1.19 seconds.

• Accident Investigations:

  In accident investigations, the length of skid marks can help determine the speed of a vehicle before braking. The speed \( v \) (in miles per hour) can be found using the formula \( v = \sqrt{24d} \), where \( d \) is the length of the skid marks in feet. If the skid marks are 360 feet long, the speed of the vehicle was approximately \( \sqrt{24 \times 360} \approx 93 \) miles per hour.

• Engineering and Construction:

  Engineers and architects use square roots in various calculations involving measurements and material properties. For example, the diagonal length of a square with side length \( s \) can be found using the Pythagorean theorem, where the diagonal is \( s\sqrt{2} \). For a square with sides of length \( \sqrt{360} \approx 18.97 \), the diagonal is approximately \( 18.97 \sqrt{2} \approx 26.82 \) units.

The square root of 360 has several interesting mathematical properties. Here are some key properties explained in detail:

• Radical Form: The simplified form of the square root of 360 is expressed as \( \sqrt{360} = 6\sqrt{10} \). This is derived by recognizing that 36 is the largest perfect square factor of 360.
• Exponential Form: The square root can also be represented in exponential form: \( 360^{1/2} \) or \( 360^{0.5} \).
• Irrational Number: The square root of 360 is an irrational number, meaning it cannot be expressed as a simple fraction. It has a non-repeating, non-terminating decimal expansion.
• Properties of Square Roots:
  • If \( x \) is the square root of a number \( X \), then both \( \sqrt{X} = x \) and \( \sqrt{X} = -x \). Therefore, \( \sqrt{360} \) also includes \( -18.973665961 \).
  • The product of the square roots of two numbers is equal to the square root of their product: \( \sqrt{a} \times \sqrt{b} = \sqrt{a \times b} \). For example, \( \sqrt{36 \times 10} = \sqrt{360} \).
• Even and Odd Properties:
  • The square root of an even number is always even if the number is a perfect square. Since 360 is not a perfect square, this property does not directly apply, but \( \sqrt{360} \) is still an irrational number.
  • If a number ends in an even number of zeros, its square root will be an integer. 360 does not end in zeros, so its square root is not an integer.
