Which numbers are irrational?
Thank you!

Answer 1

Answer: Hence,
`\sqrt{(1)/(10)},\sqrt{(1)/(8)},\sqrt{(1)/(2)}` are irrational numbers.

Explanation:

Since we have given that

4 and 16 are perfect squares.

so,
`\sqrt{(1)/(4)}=(1)/(2)\\\\and\\\\\sqrt{(1)/(16)}=(1)/(4)`

And we know that irrational numbers are those numbers which are not in the form of
`(p)/(q)`

Hence,
`\sqrt{(1)/(10)},\sqrt{(1)/(8)},\sqrt{(1)/(2)}` are irrational numbers.
