Tolong bantu jawab dengan benar.
Jawaban:
1. √27 + √300 + √12 + √75
= √9√3 + √100√3 + √4√3 + √25√3
= 3√3 + 10√3 + 2√3 + 5√3
= 20√3
2. √125 + √20 – √500
= √25√5 + √4√5 – √100√5
= 5√5 + 2√5 – 10√5
= -3√5
3. √72 – √50 + √200
= √36√2 – √25√2 + √100√2
= 6√2 – 5√2 + 10√2
= 11√2
4. √45 + √125 – √100
= √9√5 + √25√5 – 10
= 3√5 + 5√5 – 10
= -2√5
5. √18 + √8 + √72
= √9√2 + √4√2 + √36√2
= 3√2 + 2√2 + 6√2
= 11√2
