Jawaban:
1. 3√12 + 2√3
= 3√4.3 + 2√3
= 3.2√3 + 2√3
= 6√3 + 2√3
= 8√3
2. √18 + √8
= √9.2 + √4.2
= 3√2 + 2√2
= 5√2
3. √45 - √90
= √9.5 - √9.10
= 3√5 - 3√10
(ini kurang jelas angkanya, kalau salah bisa diberi tahu)
4. √1000 - 2√40
= √100.10 - 2√4.10
= 10√10 - 2.2√10
= 10√10 - 4√10
= 6√10
5. 3√2 + 3√8 - √32
= 3√2 + 3√4.2 - √16.2
= 3√2 + 3.2√2 - 4√2
= 3√2 + 6√2 - 4√2
= 5√2
