A. whole numbers,natural numbers, integers
B.irrational numbers
C. rational numbers
D. whole numbers,integers,rational numbers

Answer 1

The square root of 42 belongs under irrational numbers. By definition, irrational numbers are real numbers that when expressed in decimal form, do not repeat or terminate. Trying to find the actual value of the square root of 42 would be endless because the value does not terminate.

From the choices, the answer would be B.

Answer 2

B.Irrational number

Explanation:

We are given that a number
`√(42)`

We have to find the given number belongs to which set

We know that Rational number is that number which can be written as
`(p)/(q)` form where q is not equal to zero and p,q belongs to integers.

Irrational number : It is that number which cannot be written in
`(p)/(q)` form.

Given number is
`√(42)` which can not be written in
`(p)/(q)`

Hence, the number belongs to irrational numbers set.
