Multiplying Radicals

Multiplying Radicals Multiply numbers outside the radical with other numbers outside the radical. Multiply radicands with other radicands. Simplify, if possible

Example 1 Multiply then simplify if possible.

Example 2 Distribute then simplify if possible.

Your Turn

Dividing Radicals

Dividing Radicals Radicals with common factors will simplify You can’t leave a radical in the denominator (numerator is fine). Multiply the radical (and the numerator) by the same radical. Simplify, if possible

Example 5 Example 6

Adding and Subtracting Radicals

Add and Subtract Radicals You can only add or subtract radicals that have the EXACT SAME radicand. Then add/subtract ONLY the number OUTSIDE the radical Then, check to see if you can simplify!!

Example 1

Example 2 Sometimes you have to simplify 1st then see if you can add.
