Simplify: \(\sqrt{98} - \sqrt{32} + \sqrt{50}\)
\(8\sqrt{2}\)
Express each surd in simplest form:
\(\sqrt{98} = \sqrt{49 \times 2} = 7\sqrt{2}\)
\(\sqrt{32} = \sqrt{16 \times 2} = 4\sqrt{2}\)
\(\sqrt{50} = \sqrt{25 \times 2} = 5\sqrt{2}\)
Combine like terms:
\(7\sqrt{2} - 4\sqrt{2} + 5\sqrt{2} = 8\sqrt{2}\)
Hence, the simplified value is \(8\sqrt{2}\).
