Saya mohon bantu saya menjawab pertanyaan ini? 5√8+3√2-2√32+3√128

[tex]5 \sqrt{4.2} + 3 \sqrt{2} - 2 \sqrt{16.2} + 3 \sqrt{64.2} [/tex]
[tex] = 5.2 \sqrt{2} + 3 \sqrt{2} - 2.4 \sqrt{2} + 3.8 \sqrt{2} [/tex]
[tex] = 10 \sqrt{2} + 3 \sqrt{2} - 8 \sqrt{2 } + 24 \sqrt{2} [/tex]
[tex] = (10 + 3 - 8 + 24) \sqrt{2} [/tex]
[tex] = 29 \sqrt{2} [/tex]
