Question 559243: I am so confused on how to add and subtract radical expressions. Please help.
√2 + 3√2 - 5√3
√5 + 4√25 - 3√5
√50 + √27 - 2√5 + 7√3
I really need to be walked through the steps on how to solve these problems.

you cant add these two since the radicand is notthe same
-----------

sqrt(25)=5

since the radicands are 5 you can subtract them
