Answer:
Given that,
![((4)/(3))(\frac{\sqrt[]{6}}{2})](https://img.qammunity.org/2023/formulas/mathematics/college/kk9doqfx5h6ob5ltmwyng0bummd2yfpxd1.png)
Simplifying this we get,
![=(2)/(3)\sqrt[]{6}](https://img.qammunity.org/2023/formulas/mathematics/college/8dlj0uwq9cwroigxi2r2lxb8njrrwkxy5a.png)
we know that,
The numbers which are not a rational number are called irrational numbers.
Irrational numbers have endless non-repeating digits after the decimal point.
we get that,
![\sqrt[]{6}\text{ is an irrational number.}](https://img.qammunity.org/2023/formulas/mathematics/college/le6l6gxrydg730g1jqix2gzbj07cx933c6.png)
Hence,
![(2)/(3)\sqrt[]{6}\text{ is an irrational}](https://img.qammunity.org/2023/formulas/mathematics/college/3dw6lgpbvz8yxfw8eujviin5kxolmxv09g.png)
