Sagot :

Explanation

The question wants us to select the answer choice that shows the set of irrational numbers that is not closed under the addition.

Form the options given

[tex]\begin{gathered} \pi+(-\pi)=0 \\ is\text{ not closed} \end{gathered}[/tex]

Because,

[tex]\begin{gathered} \pi\text{ is an irrational number} \\ But\text{ 0 is a rational number} \end{gathered}[/tex]

Thus the answer is the first option

[tex]\pi+(-\pi)=0[/tex]
