Is square root of 4 a rational number

Let us first understand the meaning of square root. The square root of a number is the number that, when multiplied to itself, gives the product as the original number. Here 2 is called the square root of 4.

Real numbers that cannot be expressed as a simple fraction are known as irrational numbers. The computations based on these figures are a little more difficult. If such numbers are utilized in arithmetic operations, the values beneath the root must first be evaluated. When a rational number is divided, the output is in decimal form, which can be either ending or repeating. Irrational numbers are any numbers that are not rational numbers.

Is square root of 4 a rational number

We have already described numbers as counting numbers, whole numbers, and integers. Do you remember what the difference is among these types of numbers? What type of numbers would you get if you started with all the integers and then included all the fractions? The numbers you would have form the set of rational numbers. A rational number is a number that can be written as a ratio of two integers. We need to look at all the numbers we have used so far and verify that they are rational. The definition of rational numbers tells us that all fractions are rational. We will now look at the counting numbers, whole numbers, integers, and decimals to make sure they are rational. Are integers rational numbers? To decide if an integer is a rational number, we try to write it as a ratio of two integers. An easy way to do this is to write it as a fraction with denominator one. Since any integer can be written as the ratio of two integers, all integers are rational numbers. Remember that all the counting numbers and all the whole numbers are also integers, and so they, too, are rational. What about decimals?
