Tolong di jawab secepatnya​

Penjelasan dengan langkah-langkah:

[tex] = \frac{2}{ \sqrt{2} + 1} \times \frac{ \sqrt{2} - 1}{ \sqrt{2} - 1} [/tex]

[tex] = \frac{2( \sqrt{2} - 1) }{ \sqrt{ {2}^{2} } - {1}^{2} } [/tex]

[tex] = \frac{2 \sqrt{2} - 2 }{2 - 1} [/tex]

[tex] = \frac{2 \sqrt{2} - 2}{1} [/tex]

[tex] = 2 \sqrt{2} - 2[/tex]

Penjelasan dengan langkah-langkah:

2/(√2 + 1) = 2/(√2 + 1) . (√2 - 1)/(√2 - 1) = 2(√2 - 1)/(√2²) - (1²) = 2(√2 - 1)/(2 - 1) = 2(√2 - 1)
