[tex] \frac{10}{ 2 - \sqrt{2} } \\ = \frac{10}{ 2 - \sqrt{2} } \times \frac{2 + \sqrt{2} }{2 + \sqrt{2} } \\ = \frac{10(2 + \sqrt{2} )}{ {2}^{2} - \sqrt{ {2}^{2} } } \\ = \frac{10(2 + \sqrt{2} )}{4 - 2} \\ = \frac{10(2 + \sqrt{2}) }{2} \\ = 5(2 + \sqrt{2} )[/tex]

Penjelasan dengan langkah-langkah:
10/ 2-√2
= 10/2-√2 × 2+√2/2+√2
= 10(2+√2) / (2-√2) (2+√2)
= 20+10√2 / 4-2
= 20+10√2 / 2
