Yes.
So 3*sqrt(2) + 5*sqrt(2) = 8*sqrt(2)
But you may need to simplify terms
eg 3*sqrt(2) + 5*sqrt(8) = 3*sqrt(2) + 10*sqrt(2) = 13*sqrt(2)

How do you solve algabraic expressions?
Expressions are just expressions. Art is an expression and no one can "solve" art. You need problems to solve. In algebra, you'll most likely be looking for equations to solve. Generally you are looking for a simple way to express a variable or to equate the variable to a number. This can be done using what are called "algebraic manipulations". Usually this involves just adding, subtracting, multiplying or dividing each side of an equation (an expression need not have "sides"), however there are many, many different operations than these. wow does that suck....the answer is Elmo
