Penjelasan dengan langkah-langkah:
1. 4√14 - 2√14=
= (4- 2) √14
= 2√14
2, √12 + 2√27 =
= 2√3 + 2 (3√3)
= 2√3 + 6√3
= (2 +6) √3
= 8√3
3. √60 + √135 - √375=
= 2√15 + 3√15 - 5√15
= (2+ 3 - 5)√15
= 0√15
= 0
4. √98 - √72 =
= 7√2 - 6√2
= (7 -6)√2
= √2
5. √15 +√60 - √27 - √3=
= √15 + 2√15 - 3√3- √3
= (1 + 2)√15 + (-3 -1)√3
= 3√15 - 4√3
6. √3 + √5 + √20- √12=
= √3 + √5 + 2√5 - 2√3
= (1- 2)√3√ + (1 + 2)√5
= - √3 + 3√5
7. √6 + 3√3 + √12 + √24 =
= √6 + 3√3 + 2√3 + 2√6
= (1 + 2)√6 + (3 +2)√3
= 3√6 + 5√3
8. 2√20 - √80=
= 2(2√5)- 4√5
= 4√5 - 4√5
= 0
9. 3√32 - 2√50=
= 3 (4√2) - 2 (5√2)
= 12 √2 - 10√2
= (12-10)√2
= 2√2
10. 6√2 + 4√2 -10√2 =
= (6+ 4-10)√2
