You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.

What does radical mean in mathematics?

A radical is the sign √ which is used to indicate that a root must be calculated. The full format is n√ which indicates that it is the nth root that is required. For square roots the prefix is usually excluded. [As a result many people wrongly assume that the radical sign refers only to square roots.]


What is a radical equation?

They are actually to the one half power. You can take a factor in the radical and sqrt it and put in on the outside... Ex. sqrt(28) = sqrt(4 * 7) = sqrt(22 * 7) = 2sqrt(7) sqrt(28) = 2 * sqrt(7)

What are radical terms?

A "radical" equation is an equation in which at least one variable expression is stuck inside a radical, usually a square root. The "radical" in "radical equations" can be any root, whether a square root, a cube root, or some other root. Most of the examples in what follows use square roots as the radical, but (warning!) you should not be surprised to see an occasional cube root or fourth root in your homework or on a test.
