Question

tolongg pake cara
[tex](6 \sqrt{3} - 2 \sqrt{2} )(6 \sqrt{3} + 2 \sqrt{2} )[/tex]
​

Answer 1

Jawaban:

100

Penjelasan dengan langkah-langkah:

note:

(a+b)(a-b)=a² - b²

maka:

[tex](6 \sqrt{3} - 2 \sqrt{2} )( 6\sqrt{3} + 2 \sqrt{2} ) \\ = (6 \sqrt{3} \times 6 \sqrt{3} ) - (2 \sqrt{2} \times 2 \sqrt{2} ) \\ = 6.6. \sqrt{3} . \sqrt{3} - 2.2. \sqrt{2} . \sqrt{2} \\ = 36(3) - 4(2) \\ = 108 - 8 \\ = 100[/tex]
