Example: Add the given Radicals 3 Ö5 + 4 Ö5. Solution: Since the radicals are the same, simply add the numbers in front of the radicals. Note: Do not add the numbers under the radicals. The given two radicals are like radicals so it is easy to add them. 3 Ö5 + 4 Ö5 take Ö5 as common, (3 + 4)Ö5. Therefore, 7 Ö5.
Note: Correct: + = 5^{1/3} + 5^{1/3} = 5^{2/3}
3 Ö5 = Ö5 + Ö5 + Ö5 and
= 5^{1/3} Directions: Solve the following problems. Also write at least ten examples of your own.
