tolong bantu dong.....
Jawaban:
D.
Penjelasan dengan langkah-langkah:
[tex](2 \sqrt{2} + \sqrt{3} )(2 \sqrt{3} - \sqrt{2} ) \\ = (2 \sqrt{2} \times 2 \sqrt{3} ) + (2 \sqrt{2} \times ( - \sqrt{2} )) + ( \sqrt{3} \times 2 \sqrt{3} ) + ( \sqrt{3} \times ( - \sqrt{2} )) \\ = 4 \sqrt{6} - 2 \sqrt{4} + 2 \sqrt{9} - \sqrt{6} \\ = 3 \sqrt{6} -( 2 \times 2) + (2 \times 3) \\ = 3 \sqrt{6} - 4 + 6 \\ = 3 \sqrt{6} + 2[/tex]
