lim x → ∞ √x³ - 4x + 3 - (x-1) adalah
![]()
Jawaban:
-1
Penjelasan dengan langkah-langkah:
[tex] = \sqrt{ {x}^{2} - 4x + 3} - (x - 1) \\ = \sqrt{ {x}^{2} - 4x + 3 } - \sqrt{(x - 1) {}^{2} } \\ = \sqrt{ {x}^{2} - 4x + 3} - \sqrt{ {x}^{2} - 2x + 1 } \\ = \frac{b - q}{2 \sqrt{a} } \\ = \frac{ - 4 - ( - 2)}{2 \sqrt{1} } \\ = \frac{ - 2}{2} = - 1[/tex]
