Question 559243
{{{sqrt(2)+3sqrt(2)- 5sqrt(3)}}}

{{{4sqrt(2)-5sqrt(3)}}}

you cant add these two since the radicand is notthe same

-----------

{{{sqrt(5)+sqrt(25)-3sqrt(5)}}

{{{sqrt(5)+sqrt(5*5)-3sqrt(5)}}}
sqrt(25)=5

{{{sqrt(5)+5-3sqrt(5)}}}

since the radicands are 5 you can subtract them

{{{5-2sqrt(5)}}}

--

{{{sqrt(50)+sqrt(27)-2sqrt(5)+7sqrt(3)}}}

{{{sqrt(2*5*5)+sqrt(3*3*3)-2sqrt(5)+7sqrt(3)}}}

{{{5sqrt(2)+3sqrt(3)-2sqrt(5)+7sqrt(3)}}}

{{{5sqrt(2)+10sqrt(3)-2sqrt(5)}}}
