Question

Which expression is equivalent to the square root of 1/8

Answer 1

When you say "which," it sounds like it should be multiple choice. Anyways, here's the simplified form of
`\sqrt{\frac{1}8}}`


`\sqrt{\frac{1}8}} = (√(1))/(√(8)) = (1)/(√(8)) * (√(8))/(√(8))=\boxed{\frac{√(8)}8}`

(When simplifying fractions, you should never have a square root on the bottom. Multiply by the square root to cancel it out)
