Option B will be a rational number while options A, C and D will be irrational numbers.
What is a rational number?
A number that can be written in p/q form where q≠0 is called a rational number.
An irrational number is non-terminating and non-repeating in nature.
For example, π is an irrational number because
π =3.1415926535897.....................that is non-terminating and non-repeating and can never be written in p/q form
Similarly, a non-perfect-square number written inside a root is also an example of an irrational number.
A) π + 18
π is an irrational number while 18 is a rational number so the sum of irrational and rational will be an irrational number.
B) √25 + 1.75
√25 = 5 i.e. a rational number
1.75 is a rational number
Rational + Rational = Rational
5+1.75 = 6.75
6.75 is a rational number.
C) √3 + 5.5
√3 is an irrational number so √3 + 5.5 is an irrational number.
D) π + √2
π is an irrational number so π + √2 is an irrational number.
Hence, Option B will be a rational number while options A, C and D will be irrational numbers.
