Why does 1/sqrrt(x) = sqrrt(x) / x?
I saw a few problems similar to this while grading some of my dad's papers and it piqued my curiosity. Can anyone explain why these two equal eachother?

sqrrt(x)/x = sqrrt(x)/[sqrrt(x)*sqrrt(x)]
Then one of the sqrrt on top cancels with one on the bottom.
That's why.
