Question

What are Real Numbers? How can we denote them? Give some examples
for Irrational numbers.​

Answer 1

Answer:

Real Numbers We can represent the real numbers by the set of points on a line. The origin corresponds to the number 0. Numbers to the right of 0 are positive or > 0 and numbers to the left of 0 are negative or < 0.

Step-by-step explanation:

5/0 is an irrational number, with the denominator as zero.

π is an irrational number which has value 3.142…and is a never-ending and non-repeating number.

√2 is an irrational number, as it cannot be simplified.

0.212112111…is a rational number as it is non-recurring and non-terminating.

Answer 2

Answer :

Real numbers are the numbers which include both rational and irrational numbers. Rational numbers such as integers (-2, 0, 1), fractions(1/2, 2.5) and irrational numbers such as √3, π(22/7), etc., are all real numbers. Also, Positive or negative, large or small, whole numbers or decimal numbers are all Real Numbers.

Examples :

• π (Pi), which begins with 3.14, is one of the most common irrational numbers.

• e, also known as Euler's number, is another common irrational number.

• The Square Root of 2, written as √2, is also an irrational number.
