[tex]3 \sqrt{2} + 5 \sqrt{8} - \sqrt{32 } \\ \\ = 3 \sqrt{2} + 5 \sqrt{ {2}^{2} \times 2 } - \sqrt{ {4}^{2} \times 2 } \\ \\ = 3 \sqrt{2} + 5 \sqrt{ {2}^{2} } \times \sqrt{2} - \sqrt{ {4}^{2} } \times \sqrt{2} \\ \\ = 3 \sqrt{2} + 5 \times 2 \sqrt{2} - 4 \sqrt{2} \\ \\ = 3 \sqrt{2} + 10 \sqrt{2} - 4 \sqrt{2} \\ \\ = 9 \sqrt{2} \\ \\ \\ 3 \sqrt{50} - 2 \sqrt{18} + \sqrt{98} \\ \\ = 3 \sqrt{ {5}^{2} \times 2} - 2 \sqrt{ {3}^{2} \times 2 } + \sqrt{ {7}^{2} \times 2} \\ \\ = 3 \sqrt{ {5}^{2} } \times \sqrt{2} - 2 \sqrt{ {3}^{2} } \times \sqrt{2} + \sqrt{ {7}^{2} } \times \sqrt{2} \\ \\ = 3 \times 5 \sqrt{2} - 2 \times 3 \sqrt{2} + 7 \sqrt{2} \\ \\ = 15 \sqrt{2} - 6 \sqrt{2} + 7 \sqrt{2} \\ \\ = 16 \sqrt{2} [/tex]
