Question

I couldn’t find the radical sign so here’s the problem in a picture :)

Answer 1

√2 + 5/√50=√2 + 5/√(2*25)=√2 + 5/5√2 =√2 + 1/√2=(√2*√2)/√2 + 1/√2=
=2/√2 + 1/√2=3/√2=(3*√2)/(√2*√2)=3√2/2

Answer 2

First, you would simplify. (I don't know how to type the radical sign, so I'm just going to type radical :))
$\sqrt{2} + 1/\sqrt{2}$
Then since you can't have a radical as the denominator on the bottom, you would multiply the bottom and top by radical2 on both sides and get:
$\sqrt{2} + \sqrt{2}/2$
If you are looking for an exact answer, this would be the answer^^
If you are looking for an approximate answer, the answer would be approx. 2.12132.

Hope this helped :)
