Yes, square root of 25 is a rational number. For proving that, let’s assume that √25 is a rational number. √25 = a/b where, a, b are whole numbers and where, b is not zero. Because +5 or -5 are whole numbers and whole numbers are part of Rational Numbers. Is a square root rational or irrational?
What is the real square root of 25?
Square Root of 25. The square root of 25 is expressed as √25 in the radical form and as (25) ½ or (25) 0.5 in the exponent form. The square root of 25 is 5. It is the positive solution of the equation x 2 = 25. The number 25 is a perfect square.
Is the square root of negative 25 a rational number?
Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0. If the square root of an integer is another integer then the square is called a perfect square. For example 25 is a perfect square since
Is 2 over 15 irrational?
