Question

What is the square root of 1 over 49?

Answer 1

You can divide it for 2 different square roots, what will give you: sqrt(1)/sqrt(49)=1/7

Answer 2

Remember
$\sqrt{ \frac{x}{y} } = \frac{ \sqrt{x} }{ \sqrt{y} }$
so

$\sqrt{ \frac{1}{49} } = \frac{ \sqrt{1} }{ \sqrt{49} } = \frac{1 }{7 }$

answer is 1/7
