Square Root Basics
A square root is a mathematical operation that extracts a square root from a number. For example, the square root of 64 is 8.
The square root of a number is the positive number that, when multiplied by itself, gives the original number. In other words, the square root of a number is the length of the hypotenuse of a right triangle with the other two sides being the number and 1.

1. Introduction
The current study aimed to investigate the relationship between EFL learners’ oral proficiency and their writing performance. The study also aimed to identify the possible factors that might affect EFL learners’ oral proficiency and writing performance. To achieve these objectives, the study employed a correlational design. The participants of the study were 120 EFL learners who were studying at different universities in Iran. The participants’ oral proficiency was assessed using the Oxford Placement Test (OPT) and their writing performance was assessed using the Test of Written English (TWE). The data were analyzed using Pearson’s correlation coefficient. The results of the study showed that there was a significant positive relationship between EFL learners’ oral proficiency and their writing performance. Additionally, the results of the study showed that there were some factors that affected EFL learners’ oral proficiency and writing performance. These factors were: EFL learners’ gender, EFL learners’ major, and EFL learners’ level of education.
Square Root Basics
A square root is a mathematical function that extracts the square root of a number. The square root of a number is the number that, when multiplied by itself, results in the original number. For example, the square root of 9 is 3, because 3 multiplied by 3 results in 9.
The square root of a number can be found using a calculator, or by hand using a series of steps. To find the square root of a number by hand, first divide the number by 2. If the number is even, the square root is the number found in the middle of the divided number. If the number is odd, the square root is the number found at the beginning of the divided number. Then, take the square root of the number found in step 1.
For example, to find the square root of 25 by hand, divide 25 by 2. The result is 12.5. Take the square root of 12.5, which is 5.
Square Root Definition
The square root of a number is the number that results when the number is multiplied by itself and then divided by two.
Methods to Find Square Root of a Number
There are three methods to find the square root of a number:
Method 1: Trial and Error
This is the most common method, and it is used to find the approximate square root of a number. You start by trying a number that is close to the square root of the number you are trying to find. You then keep trying numbers that are closer and closer to the square root until you find the number that is equal to the square root of the number you are trying to find.
Method 2: The Quadratic Formula
This is a more accurate method to find the square root of a number. You use the quadratic formula to find the roots of a quadratic equation. One of the roots will be the square root of the number you are trying to find.
Method 3: Newton’s Method
This is a more accurate method than the quadratic formula. It is used to find the roots of a non-linear equation. One of the roots will be the square root of the number you are trying to find.
How to Find the Square Root of a Number by Prime Factorization Method?
The square root of a number can be found by prime factorization method. The prime factorization of a number is the decomposition of the number into its prime factors. The prime factors of a number are the prime numbers that divide into the number without a remainder.
To find the square root of a number by prime factorization method, first find the prime factors of the number. Next, write the number as the product of its prime factors. Finally, take the square root of the product.
For example, the prime factors of 36 are 2, 3, and 6. Therefore, 36 can be written as the product of 2, 3, and 6 as 2 x 3 x 6 = 36. The square root of 36 is 6.

The United States has a long and rich history with the bicycle. From the early days of the penny-farthing to high-tech racing bikes, Americans have embraced the bicycle as a form of transportation and recreation.
The first pedal-powered bicycles were developed in the 1860s. These “velocipedes” had large front wheels and small rear wheels, and were propelled by pedals that turned the front wheel. In 1868, American blacksmith Kirkpatrick Macmillan invented the first bicycle that could be propelled by the rider’s feet.
The modern bicycle was developed in the late 1800s. The “safety bicycle” had two equal-sized wheels and a chain-driven rear wheel. This type of bicycle became popular in the United States and Europe, and remains the most common type of bicycle today.
The popularity of the bicycle grew in the early 1900s. In 1903, the League of American Wheelmen (now known as the League of American Bicyclists) was founded to promote the use of the bicycle. That same year, the first Tour de France bicycle race was held.
The popularity of the bicycle continued to grow in the United States in the mid-1900s. In 1965, Congress passed the Highway Safety Act, which provided funding for the development of bicycle lanes and trails. In 1975, the Bicycle Helmet Safety Institute was founded to promote the use of helmets.
Today, the bicycle
