Irrational Numbers: Numbers that cannot be expressed as a ratio of two ...
The free rational or irrational calculator can be used to find out if the entered number is rational or irrational. ... If the number of digits after the decimal point are finite, then it is called the terminating rational number. For example: 1/4 = 0.25. 2/4 = 0.5, and.
To determine whether 25 is rational or irrational, we first need to calculate its value. We find the square root of 25: 25 = 5 This is because 5 multiplied by itself (5 x 5) equals 25. Next, we define what a rational number is. A rational number is any number that can be expressed as a fraction, q p , where p and q are integers and q is not zero.
But √4 = 2 is rational, and √9 = 3 is rational ..... so not all roots are irrational. Note on Multiplying Irrational Numbers. Multiplying irrational numbers can be surprising! Have a look at this: π × π = π 2 is known to be irrational; But √2 × √2 = 2 is rational; So multiplying irrational numbers might result in a rational number.
Here we look at whether a square root is irrational ... or not! Rational Numbers. A "Rational" Number can be written as a "Ratio", or fraction. Example: 1.5 is rational, because it can be written as the ratio 3/2. Example: 7 is rational, because it can be written as the ratio 7/1.

Adding a rational number to an irrational number gives an irrational number. Example: 2 + √3 is irrational. Multiplying an irrational number by a nonzero rational number is still irrational. Example: 5 × √2 is irrational. Two irrational numbers added or multiplied might give a rational result—or might not.
