The cube root of 48 and the square root of 80 are both irrational numbers since they cannot be expressed as a fraction or a repeating decimal. The value 9.83 repeating can be expressed as a repeating decimal, so it is also irrational.
Therefore, the value that is not an irrational number is π, which is a well-known irrational number.
The answer is b) π.
Which of the following values is not an irrational number?
pi, the cube root of 48, 9.83 repeating where the 3 is repeating, and the square root of 80
a) 9.83 repeating where the 3 is repeating
b) π
c) the cube root of 48
