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
