1. Jawaban PersatuanWibu
1) = √3 (√6) - √3 (√2) + √2 (√6) - √2 (√2)
= √3 (√6) - √6 + √2 (√6) - 2
= (√3 - 1 + √2) √6 - 2
= 2,15√6 - 2
2) = 5√2 (√2) - 5√2 (3√3) + √3 (√2) - √3 (3√3)
= 5 (2) - 15 √3 (√2) + √3 (√2) - 3 (3)
= 10 - 14 √3(√2) - 9
= 1 - 14√3 (√2)
= 1 - 14√6
3) = 7√3 (√3) + 7√3 (2√2) - √2 (√3) - √2 (2√2)
= 7 (3) + 14 √3 (√2) - √3 (√2) - 2 (2)
= 21 + 13√3 (√2) - 4
= 17 + 13√6
