1.231241251261271. is an irrational number?
No, it is rational. Numbers whose decimal digits either stop or repeat can be written as a fraction and so are rational.
Find two irrational numbers whose product is a rational number?
root 2 * root 2 = 2
How are irrational numbers being used in the world?
There are very many uses for irrational numbers. A square, whose sides are a rational number, will have a diagonal of irrational length. The diagonals of most rectangles, with rational sides, will be irrational. The circumference and area of a circle (or ellipse) is related to pi, an irrational number. In the same way that pi is central to geometry, another irrational number, e, is fundamental to advanced calculus.
Is the square root of 2 imaginary?
No, but it is irrational, because there is no rational number whose square is two. Imaginary numbers are the square roots of negative numbers.
Is an irrational number a number that goes on forever?
An irrational number is a number that can't be written as a fraction with whole numbers on top and bottom.An irrational number written as a decimal never ends. BUT, some rational numbersdo the same thing, so you can't say that just because the decimal never ends, itmust be an irrational number.Here are some rational numbers whose decimals never end:1/31/61/71/91/11
Is the number 0.112123123412345. a rational or irrational number?
It's rational. It can be written as the quotient of two numbers whose HCF is one.

Give Two different irrational numbers whose sum is a rational number?
1 + pi, 1 - pi. Their sum is 2.
What is the significance of irrational numbers with explanation?
A rational number is a number which can be expressed as a ratio of two integers. However, there are far more numbers that cannot be expressed in this fashion.The set of rational numbers is not closed under the basic operation of taking square roots. There are also other operations whose results are not rational numbers. The two most important constant of mathematics are pi (geometry) and e (calculus) and both are irrational numbers.

A short note on square root of rational number?
Square root of a rational number may either be rational or irrational. For example 1/4 is a rational number whose square root is 1/2. Similarly, 4 is 4/1 which is rational and the square root is 2 which of course is also rational. However, 1/2 and 2 are rational, but their square roots are irrational. We can say the square root of a rational number is always a real number. We can also say the rational numbers whose square roots are also rational are perfect squares or fractions involving perfect squares.
