The sq. root of a quantity is each constructive and damaging of the numerical worth we acquire utilizing totally different strategies. On this mini-lesson, we are going to calculate the sq. root of 18 by prime factorization and lengthy division methodology together with few attention-grabbing issues.

• Sq. root of 18: 18 = 4.2426
• Sq. of 18: 18² = 324

1. What Is the Sq. Root of 18? 2. Is Sq. Root of 18 Rational or Irrational? 3. Tips on how to Discover the Sq. Root of 18? 4. Necessary Notes on Sq. Root of 18 5. Difficult Questions 6. FAQs on Sq. Root of 18

• The sq. root of a quantity is the quantity when multiplied by itself leads to the unique quantity.
• The sq. root of 18 is written as 18 = 4.2426
• Sq. root of 18 in radical type = 18 = (2 × 3 × 3) = 3√2
• Therefore, 18 will not be an ideal sq.
• A rational quantity is outlined as a quantity that may be expressed within the type of p/q the place q 0
• The sq. root of 18 is a non-repeating and non-terminating quantity. Therefore, the sq. root of 18 can’t be represented as a ratio of two integers.
• Subsequently, the sq. root of 18 is an irrational quantity.

The sq. of 18 will be evaluated utilizing the prime factorization methodology or lengthy division methodology.

### Sq. Root of 18 by Prime Factorization Technique

To search out the sq. root of 18 firstly we are going to discover the prime factorization of 18 18 = 2 × 3 × 3 18 = 2 × 32 Now this may be simplified into √18 = √(2 × 32) √18 = √2 × √ 32 18 = 3√2 Subsequently, the sq. root of 18 will be simplified as √18 = 3√2

### Sq. Root of 18 By Lengthy Division

With the assistance of the next steps, we are able to discover the sq. root of 18 through the lengthy division methodology.

• Write 18 as proven within the diagram. Begin grouping the digits from the best finish by placing a bar on high of them.
• Now discover a quantity which when multiplied with itself provides a quantity lower than equal to 18. We all know that 4 × 4 = 16
• Calculate the distinction as achieved within the typical division and add the divisor with itself that was calculated within the earlier half. The divisor will grow to be 8 and the rest will probably be 2.
• Now we’ve got no extra quantity within the dividend left so, we put a decimal level after the dividend and quotient. Then place 4 pairs of zeros after the decimal of the dividend and convey the pair of zeros down.
• Discover a quantity for the unit’s place of divisor such that can lead to a quantity lower than equal to 200.
• Carry the subsequent pair of zeros down and repeat the steps until the final pair of zeros.
• Subsequently, we get the sq. root of √18 = 4.2426 by the lengthy division methodology.
