Question

√27,√8,√12 рациональные числа или иррациональные?

Answer 1

Ну, конечно же, что это иррациональные числа. 

Answer 2

To determine whether √27, √8, and √12 are rational or irrational numbers, we need to consider if their square roots can be expressed as fractions (rational) or not (irrational).

1. √27: √27 is an irrational number because it cannot be expressed as a fraction or terminated decimal. Its decimal approximation is approximately 5.196152.

2. √8: √8 is an irrational number as well. It cannot be expressed as a fraction or terminated decimal. Its decimal approximation is approximately 2.828427.

3. √12: √12 is also an irrational number. It cannot be expressed as a fraction or terminated decimal. Its decimal approximation is approximately 3.464102.

Therefore, all three square roots (√27, √8, and √12) are irrational numbers.
