`========================================`

is the product of an irrational number and an irrational number always irrational?

We can easily check that by just multiplying some irrational numbers on our calculator.

Let's take

`\pmb{√(2) }` times
`\pmb{√(5) }`

Multiply:-

The result is an irrational number.

Let's try to multiply π times itself.

Once again, we have an
`\pmb{irrational}` number.

Hence, the answer is:-

`\pmb{Always~True}`
