Perkalian distributif bentuk akar.
Jawaban:
1. 12√3 + 12√2
2. 12√5 + 14√6
3. 4√3 – 16√2
4. 8√5 + 6√6
5. 4√3 – 16
Penjelasan dengan langkah-langkah:
1. (2√3 + 4√2) (6√3 + 3√2)
= (2√3 x 6√3) + (4√2 x 3√2)
= 12√3 + 12√2
2. (3√5 + 7√6) (4√5 + 2√6)
= (3√5 x 4√5) + (7√6 x 2√6)
= 12√5 + 14√6
3. (2√3 + 4√2) (2√3 – 4√2)
= (2√3 × 2√3) – (4√2 × 4√2)
= 4√3 – 16√2
4. (2√5 – 3√6) (4√5 – 2√6)
= (2√5 × 4√5) + (3√6 × 2√6)
= 8√5 + 6√6
5. (2√3 + 4) (2√3 – 4)
= (2√3 × 2√3) – (4 × 4)
= 4√3 – 16
