Square Roots 平方根😸
Mathematics is the most traditional and international field of not only science but also the all academic field. I am writing about Math in English recently to announce the brief idea.
When a certain number squared is x, that is called the square root of x. There are 2 square roots of 9, positive 3 and negative 3. The square root of 0 is only 0. There is supposed to be no square root of nagative number.
Let's think about the square root of 3. There is no whole number that becomes 2 when it is squared. The positive square root of 3 is one point seven three two zero five zero eight... it is a decimal that continues without limit. The square root of 3 is positive the square root of 3 and negative the square root of 3.
