The process is the same for addition and subtraction.
The process is totally different for like and unlike terms.
to simplify the radicand
A radical integer is a number obtained by closing the integers under addition, multiplication, subtraction, and root extraction.
Radical (3x) = radical(x) * radical(3).
"rationalizing" the denominator
The answer depends on the form of the radical expression.
radical expressiona radical expression
A rational expression is an expression that contains a radical, i.e., a root.
10*radical(2).
They can always be combined for multiplication. For division, the only requirement is that the denominator is not 0. For addition and subtraction the terms, after simplification, must have identical radicals.So, for example, sqrt(18) + sqrt(50) can be simplified to 3*sqrt(2) + 5*sqrt(2) and that simplifies to 8*sqrt(2).
A radical expression is an expression that involves a square root, cubic root, etc.
