Let's simplify each of the radical expressions provided:
-
√54:
- √54 = √(9 * 6) = √9 * √6 = 3√6.
-
√12:
- √12 = √(4 * 3) = √4 * √3 = 2√3.
-
√18:
- √18 = √(9 * 2) = √9 * √2 = 3√2.
-
√45:
- √45 = √(9 * 5) = √9 * √5 = 3√5.
-
2√3:
- This is already in simplified form.
-
3√2:
- This is already in simplified form.
-
3√5 * 3√6:
- (3√5)(3√6) = 9√(5 * 6) = 9√30.
Now, let’s match the given problems to their corresponding simplified radicals:
- √54 = 3√6
- √12 = 2√3
- √18 = 3√2
- √45 = 3√5
- 2√3 = 2√3
- 3√2 = 3√2
- 3√5 * 3√6 = 9√30 (not listed in your options)
So the matches are:
- √54 → 3√6
- √12 → 2√3
- √18 → 3√2
- √45 → 3√5
- 2√3 → 2√3
- 3√2 → 3√2
- 3√5 * 3√6 → 9√30 (not listed, but calculated).
