Pendahuluan

[tex] (\sqrt{x} ) {}^{2} = x \\ \\ ( \sqrt[3]{x} ) {}^{3} = x[/tex]

Penyelesaian

[tex]( \sqrt{2} - \sqrt{3} )( \sqrt{2} + \sqrt{3} ) \\ \\ = ( (\sqrt{2}) {}^{2}) - (( \sqrt{3} ){}^{2} ) \\ \\ = (\sqrt{2 \times 2} ) - ( \sqrt{3 \times 3} ) \\ \\ = (\sqrt{4} ) - ( \sqrt{9} ) \\ \\ = (2) - (3) \\ \\ = 2 - 3 \\ \\ = \red{ - 1}[/tex]

Kesimpulan

Jadi, jawaban yang tepat adalah -1

Penjelasan dengan langkah-langkah:

(√2 - √3)(√2 + √3)

√2² - √3²

2 - 3

-1
