Answer 1

Let's check every one of them:

`\sqrt[]{4}+\sqrt[]{16}=2+4=6,\text{ it's not irrational}`
`\sqrt[]{5}+\sqrt[]{36}=\sqrt[]{5}+6,\text{ it is irrational}`
`\sqrt[]{9}+\sqrt[]{24}=3+\sqrt[]{24},\text{ it is irrational}`
`2\cdot\sqrt[]{4}=2\cdot2=4,\text{ it is not irrational}`
`\sqrt[]{49}\cdot\sqrt[]{81}=7\cdot9=63,\text{ it is not irrational}`
`3\cdot\sqrt[]{12}=6\sqrt[]{3},\text{ it is irrational}`
