  2. To multiply or divide radicals, we do it just like multiply or divide polynomials, and then we need to simplify if applicable. We cannot combine 2x + 2y or 2x – 2y, but we can do 2x ∙ 2y or 2x ÷ 2y • Therefore, we can multiply or divide radicals with same or different radicands, but the indices must be the same For instance: is OK but 2 is OK but 25

  3. More examples Multiply then simplify = =
