What is the square root of a number?
In mathematics, a square root of a number x is a number y such that y2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16, because 42 = (−4)2 = 16.
What is the value of √?
The square root of 2 or root 2 is represented using the square root symbol √ and written as √ 2 whose value is 1.414. This value is widely used in mathematics. Root 2 is an irrational number as it cannot be expressed as a fraction and has an infinite number of decimals.
What is a square root of 1?
List of Perfect Squares
Is 4 a perfect square?
For instance, the product of a number 2 by itself is 4. In this case, 4 is termed as a perfect square. A square of a number is denoted as n × n. Example 1.
|2 x 2||4|
|3 x 3||9|
|4 x 4||16|
|5 x 5||25|
Why is it called a square root?
The idea of the square root existed in Egypt and the technical term for it was Knbt, literally “corner” or “angle.” Peet has the explanation for that, that the length of each of the two sides of a square containing any corner of it was its square root.
What is the root square of 25?
The square roots of 25 are √25=5 and −√25=−5 since 52=25 and (−5)2=25. The principal square root of 25 is √25=5. Example 2: Find the real roots of the equation x2=100.
What is the square of 8?

What is the value of I in maths?
The value of i is √-1. The imaginary unit number is used to express the complex numbers, where i is defined as imaginary or unit imaginary. We will explain here imaginary numbers rules and chart, which are used in Mathematical calculations.
Is 1 is a perfect square?
Squaring, which we learned about in a previous lesson (exponents), has an inverse too, called “finding the square root.” Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 …
Does 0 have a square root?
Zero has one square root which is 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can ‘t be written as the quotient of two integers. The decimal form of an irrational number will neither terminate nor repeat.
