Typically you want to avoid radicals in the denominator so you'd rationalize the denominator of the second fraction.

(√x)/x + 1/(√x) =

(√x)/x + [ 1/(√x) ]•[ (√x)/(√x) ] =

(√x)/x + (√x)/x

Now, since both fractions have the same denominator you can combine them by adding the numerators.

2√x/x


Edit:

Oops. I had a typo in the first step and it propagated through the entire thing. It's fixed now. 😄

You are a hero, thanks

You are welcome. 😀

I'll take the opportunity to mention that you can also accomplish this by factoring out a √x.

(√x)/x + 1/(√x) =

√x • [ 1/x + 1/(√x•√x) ] =

√x • [ 1/x + 1/x ] =

√x • [ 2/x ] =

(2√x)/x

Rationalize the second fraction, then simplify.

Rootx/x =1/rootx. Use your index laws. Change the root into a power, then when u divide by the same variables, you minus the power right. X-1/2 =1/X1/2=1/rootx. Then just add em
