Square Root of 5400

The square root is the inverse of the square of the number. 5400 is not a perfect square. The square root of 5400 is expressed in both radical and exponential form. In radical form, it is expressed as √5400, whereas 5400^(1/2) in exponential form. √5400 ≈ 73.48469, which is an irrational number because it cannot be expressed in the form of p/q, where p and q are integers and q ≠ 0.

The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, the prime factorization method is not used; instead, the long division method and approximation method are used. Let us now learn the following methods:

• Prime factorization method
• Long division method
• Approximation method

The product of prime factors is the prime factorization of a number. Now let us look at how 5400 is broken down into its prime factors.

Step 1: Finding the prime factors of 5400 Breaking it down, we get 2 x 2 x 2 x 3 x 3 x 3 x 5 x 5: 2^3 x 3^3 x 5^2

Step 2: Now we found out the prime factors of 5400. The second step is to make pairs of those prime factors. Since 5400 is not a perfect square, the digits cannot be grouped perfectly into pairs, but we can simplify √5400 = √(2^3 x 3^3 x 5^2) = 2 x 3 x 5 x √6 = 30√6.

The long division method is particularly used for non-perfect square numbers. In this method, we should check the closest perfect square number for the given number. Let us now learn how to find the square root using the long division method, step by step.

Step 1: To begin with, we need to group the numbers from right to left. For 5400, we group it as 54 and 00.

Step 2: Now we need to find n whose square is less than or equal to 54. We can say n is 7 because 7 x 7 = 49, which is less than 54. Now, the quotient is 7, and after subtracting 49 from 54, the remainder is 5.

Step 3: Bring down 00, making the new dividend 500. Add the previous divisor with the quotient, 7 + 7 = 14, making 140 our new divisor.

Step 4: Find the value of n where 14n x n ≤ 500. Let n be 3. 143 x 3 = 429.

Step 5: Subtract 429 from 500, leaving a remainder of 71.

Step 6: Since the dividend is less than the divisor, add a decimal point and bring down two zeros, making the dividend 7100.

Step 7: Find the new divisor, 146, where 146n x n ≤ 7100. Let n be 4. 1464 x 4 = 5856.

Step 8: Subtract 5856 from 7100, leaving a remainder of 1244.

Step 9: Now the quotient is 73.4.

Step 10: Continue the steps until you get two numbers after the decimal point.

So, the square root of √5400 is approximately 73.48.

The approximation method is another way to find square roots. It's an easy method to estimate the square root of a given number. Now, let us learn how to find the square root of 5400 using the approximation method.

Step 1: We need to find the closest perfect squares to √5400.

The smallest perfect square below 5400 is 4900, and the largest perfect square above 5400 is 5776. √5400 falls between 70 and 76.

Step 2: Apply the formula: (Given number - smallest perfect square) / (Greater perfect square - smallest perfect square) Using the formula: (5400 - 4900) / (5776 - 4900) = 500 / 876 = 0.57

Using the formula, we identified the decimal point of our square root. Add this value to the integer part of the root, 70 + 0.57 = 70.57, so the approximate square root of 5400 is 73.48.

• Square root: A square root is the inverse of a square. For example, 4^2 = 16, and the inverse of the square is the square root, so √16 = 4.

• Irrational number: An irrational number is a number that cannot be written in the form of p/q, where q is not equal to zero, and p and q are integers.

• Principal square root: A number has both positive and negative square roots; however, the positive square root is more commonly used due to its real-world applications. This is known as the principal square root.

• Prime factorization: Breaking down a number into its basic prime number factors. For example, 5400 = 2^3 x 3^3 x 5^2.

• Long division method: A step-by-step method of dividing numbers to find the square root, often used when estimating roots of non-perfect squares.
