Question

which is the rationalized form of the expression the square root of x divided by the square root of x +the square root of 7

Answer 1

I assume your goal is to rationalize the denominator -

So you need to multiply the denominator by its conjugate.

So we have:

`(√(x) )/(√(x)-√(7) ) *(√(x) +√(7) )/(√(x) +√(7))`

->

`(x-√(7)√(x) )/(x-7)`
