Question

Which of the following sets does the number √49 belong to? Whole Numbers, Integers, Rational Numbers, Irrational Numbers, Real Numbers, None of the Above

a) Whole Numbers
b) Integers
c) Rational Numbers
d) Real Numbers

Answer 1

The number √49 belongs to the sets of Whole Numbers, Integers, Rational Numbers, and Real Numbers.

Step-by-step explanation:

The number √49 belongs to the following sets:

1. Whole Numbers: Whole numbers include all the positive integers, including 0. Since 7 is a positive integer, √49 is a whole number.
2. Integers: Integers are whole numbers and their negative counterparts. √49 is a positive integer, so it is an integer.
3. Rational Numbers: Rational numbers are numbers that can be expressed as a fraction or a ratio of two integers. √49 can be expressed as 7/1, so it is a rational number.
4. Real Numbers: Real numbers include all rational and irrational numbers. Since √49 is a rational number, it is also a real number.

Therefore, the correct answer is d) Real Numbers.
