If a number is multiplied by itself, the result is a square. The inverse of the square is a square root. The square root is used in fields such as vehicle design, finance, etc. Here, we will discuss the square root of 348.
The square root is the inverse of squaring a number. 348 is not a perfect square. The square root of 348 can be expressed in both radical and exponential form. In radical form, it is expressed as √348, whereas in exponential form it is expressed as (348)^(1/2). √348 ≈ 18.65475, which is an irrational number because it cannot be expressed as a ratio of two integers.
The prime factorization method is used for perfect square numbers. However, for non-perfect square numbers, methods like the long division method and approximation method are used. Let's learn these methods:
Prime factorization involves expressing a number as a product of its prime factors. Here's how we break down 348 into its prime factors:
Step 1: Find the prime factors of 348. Breaking it down, we get 2 x 2 x 3 x 29: 2^2 x 3^1 x 29^1
Step 2: We found the prime factors of 348. Since 348 is not a perfect square, the digits cannot be grouped into pairs for exact calculation, making prime factorization insufficient for exact square root calculation.
The long division method is useful for non-perfect square numbers. This method involves finding the closest perfect squares. Let's see how to find the square root using long division, step by step:
Step 1: Group the numbers from right to left. For 348, group as 48 and 3.
Step 2: Find n such that n^2 is ≤ 3. Here, n = 1 since 1^2 ≤ 3. Subtract 1 from 3, remainder is 2.
Step 3: Bring down the next pair to get 248. Double the divisor (1 + 1 = 2) to form a new divisor.
Step 4: Find n such that 2n x n ≤ 248. Choose n as 8, since 28 x 8 = 224.
Step 5: Subtract 224 from 248, remainder is 24.
Step 6: Bring down the next pair (00) to form 2400. Add a decimal point to quotient.
Step 7: Find the new divisor as 289. Calculate 289 x 8 = 2312.
Step 8: Subtract 2312 from 2400, remainder is 88.
Step 9: Continue the steps until desired precision. Quotient is approximately 18.65.
The approximation method is a straightforward way to find square roots. Here's how to approximate the square root of 348:
Step 1: Identify the nearest perfect squares surrounding 348. The closest perfect squares are 324 (18^2) and 361 (19^2). √348 lies between 18 and 19.
Step 2: Apply the formula: (Given number - smaller perfect square) ÷ (larger perfect square - smaller perfect square). (348 - 324) ÷ (361 - 324) = 24 ÷ 37 ≈ 0.6486 Add this decimal to the smaller base: 18 + 0.6486 = 18.6486. So, the square root of 348 ≈ 18.65.
Students often make mistakes in finding square roots, such as forgetting the negative square root or skipping important steps like the long division method. Let's review some common mistakes in detail.
Can you help Max find the area of a square if its side length is given as √348?
The area of the square is approximately 348 square units.
The area of a square = side².
Given side length is √348.
Area = (√348)² = 348 square units.
Therefore, the area is approximately 348 square units.
A square-shaped building measuring 348 square feet is built; if each side is √348, what will be the square feet of half of the building?
174 square feet
Since the building is square-shaped, divide the total area by 2 to find half the area. 348 ÷ 2 = 174
Thus, half of the building measures 174 square feet.
Calculate √348 x 5.
Approximately 93.27
First, find the square root of 348, approximately 18.65.
Multiply 18.65 by 5. 18.65 x 5 ≈ 93.27
What will be the square root of (348 + 4)?
The square root is 19.
Calculate the sum: 348 + 4 = 352. Find the square root of 352: √352 ≈ 18.76.
Therefore, the square root of (348 + 4) is approximately ±18.76.
Find the perimeter of a rectangle if its length 'l' is √348 units and the width 'w' is 38 units.
The perimeter is approximately 113.3 units.
Perimeter of a rectangle = 2 × (length + width)
Perimeter = 2 × (√348 + 38) = 2 × (18.65 + 38) ≈ 2 × 56.65 ≈ 113.3 units.
