Decimal Form
The square root of 180 in decimal form is approximately 13.416. This is a non-repeating, non-terminating decimal.
Prime Factorization Method
To find the square root of 180 using the prime factorization method, follow these steps:
- Find the prime factors of 180: 180 = 2 × 2 × 3 × 3 × 5
- Group the prime factors into pairs: (2 × 2), (3 × 3), 5
- Take the square root of each pair: √(2 × 2) = 2, √(3 × 3) = 3
- Multiply the results: 2 × 3 × √5 = 6√5
Thus, the simplified form of the square root of 180 is 6√5.
Long Division Method
The long division method can be used to find the square root of 180 more accurately:
- Pair the digits of 180 from right to left.
- Find the largest number whose square is less than or equal to the leftmost pair.
- Subtract the square of this number from the pair and bring down the next pair.
- Double the quotient and find a new digit to append to the quotient such that the new divisor times this digit is less than or equal to the dividend.
- Repeat until the desired precision is achieved.
Visual Representation
A visual way to represent the square root of 180 is through a number line or a geometric figure, demonstrating the length of the side of a square with an area of 180 square units.
Applications
The square root of 180 is used in various mathematical calculations, including geometry, algebra, and real-world applications such as engineering and physics. Understanding how to simplify and calculate it is essential for solving many practical problems.
