Question

I'm not even sure how to do this

Answer 1

Remember this information:

`\sqrt{(a)/(b)} = (√(a))/(√(b))`

(Essentially, the square root of a fraction is equal to the square root of the numerator over the square root of the denominator.)

Applying that rule, we find:

`\sqrt{(1)/(49)} = (√(1))/(√(49)) = \pm (1)/(7)`

The final answer is
`\boxed{\pm (1)/(7)}`.
