Answer: 3. 4 2/3 ÷ √4/8           4. 4 2/3 - √4/8

Step-by-step explanation:

irrational number will never be changed into rational number when they do any operation with rational numbers.

4 2/3 is a rational number, which means the second term in the expression must be rational in order to make the expression entirely rational

√3 is not rational, thus, all the expressions that contains √3 is irrational.

The remaining have √4, but √4 is rational because simplifying it will become 2, and so expressions with √4 is rational

Answer:

Third and fourth.

Step-by-step explanation:

The first one is not because the second number is not rational; [tex]\sqrt{3}[/tex] is not rational.

The second one is not either for the above reason.

The third is because [tex]\sqrt{4}[/tex] is 2, which is rational.

Also the fourth for the previous reason.

And not the fifth for the first reason.
