Question

List two differences between how radicals are multiplied and how they are added or subtracted. In 1 sentence.

Answer 1

When multiplying radicals, you can multiply the radicands (the numbers inside the radicals) directly and simplify, whereas when adding or subtracting radicals, you must ensure they have the same radicand (and index) to combine them, similar to combining like terms.
