## How to discover the Square root of 343?

The square source of 343 or any kind of number deserve to be calculation in countless ways. 2 of them are the prime administer method and the long division method.

### Square root of 343 in its easiest Radical Form

The square root of 343 is expressed in the radical kind as √343. This have the right to be streamlined using the prime factorization. Permit us 343 together a product of its prime factors. 343 = 7 × 7 × 7. √343 = √(7 × 7 × 7) = 7√7

### Square source of 343 by the Long division Method

The long division method helps us to discover a an ext accurate worth of square root of any number. The complying with are the steps to advice the square source of 343 by the long division method.

Step 1: compose 343.000000. Take the number in pairs from the right. 1 was standing alone. Now division 3 through a number such that (number × number) offers ≤ 3.Obtain quotient = 1 and also remainder = 1. Double the quotient. We acquire 2. Have actually 20 as our new divisor. Bring under 43 for division.Step 2: Find a number such that (20 + that number) × that number offers the product ≤ 2 43. We uncover that 28 × 8 = 2 24.Subtract native 2 43 and get 19 together the remainder. Carry down the pair that zeros. 19 00 is our new divisor.Step 3:18 is our quotient and on doubling it becomes 36 and also 360 is our new divisor. Find a number such the (360 + the number) × number it s okay 19 00 or much less than that. We find 365 × 5 = 18 25. Subtract this native 19 00 and also get the remainder and bring under the zeros. 75 00 becomes the new dividend.Repeat the procedures until us approximate the square root to 3 decimal places. √343 = 18.520 Explore Square roots using illustrations and interactive examples:

Example 1: Sandy has to buy a table fabric that could cover the rectangular coffee table of length as twice as that width. What is the length of the towel that she has to purchase if the area the the table is 686 sq inches?

Solution:

Area of the rectangle = length × broad sq incheslength = 2 × width inchesArea the the rectangle = 2 × width × width = 686 sq inches2 width2 = 686 sq incheswidth2 = 686 ÷ 2 = 343 inchesWidth = √343 = 18.52 Length = 2 × width = 2 × 18.52 = 37.04 Length the the coffee table = 37.04 inchesShe needs to purchase a few inches longer than her coffee table, preferably 40 inches long cloth.

Example 2: Evaluate: √343 × √175

Solution:

√343 = √(7 × 7 ×7) = 7√7√175 = √(5 × 5 × 7) = 5√7=√343 × √175 = 7√7 × 5√7 =√7 × √7 × 5 × 7 = 7 × 35 = 245=√343 × √175 = 245
