Tentukan hasil perkalian bentuk akar berikut. Tolong bantuannya sama caranya plissss

(2√3 + 3√7)(4√3-√7)
2√3. 4√3 - 2√3.√7 + 3√7.4√3 - 3√7.√7
8.3 - 2√21 + 12√21 - 3.7
24 + 10√21 - 21 = 3 + 10√21

MAPEL = MATEMATIKA
BAB AKAR

[tex](2 \sqrt{3} + 3 \sqrt{7} )(4 \sqrt{3} - \sqrt{7} ) \\ =8 \sqrt{9} - 2 \sqrt{21} + 12 \sqrt{21} - 3 \sqrt{49} \\ = 8 \times 3 + 10 \sqrt{21} - 3 \times 7 \\ = 24 + 10 \sqrt{21} - 21 \\ = 3 + 10 \sqrt{21} [/tex]

semoga membantu
