No 01 Test Preparation (Basic) The result of \(\sqrt{160} - \sqrt{90}\) is ... (A) \(\sqrt{10}\) (B) \(2\sqrt{10}\) (C) \(3\sqrt{10}\) (D) \(\sqrt{50}\) Show Solution Answer: A \begin{equation*} \begin{split} \sqrt{160} - \sqrt{90}& = \sqrt{16 \times 10} - \sqrt{9\times 10}\\\\ \sqrt{160} - \sqrt{90}& = 4\sqrt{10} - 3\sqrt{10}\\\\ \sqrt{160} - \sqrt{90}& = \sqrt{10} \end{split} \end{equation*} (Next Lesson) No 02 Kembali ke Test Preparation (Basic)
