hasil dari 3akar8-akar50+2akar18..dengan caranya

3√8-√50+2√18
=3√4×2-√25×2+2√9×2
= 3×2√2-5√2+2×3√2
=6√2-5√2+6√2
=7√2

maaf jika ada kesalahn

[tex]3 \sqrt{8 }- \sqrt{50} + 2 \sqrt{18} \\ = 3 \sqrt{2 {}^{3} } - \sqrt{2 \times 5 {}^{2} } + 2 \sqrt{2 \times 3{}^{2}} \\ = 3 \times 2 \sqrt{2 } - 5 \sqrt{2} + 2 \times 3 \sqrt{2} \\ =6 \sqrt{2} - 5 \sqrt{2} + 6 \sqrt{2} \\ = 1 \sqrt{2} + 6 \sqrt{2} \\ = 7 \sqrt{2} [/tex]
SEMOGA MEMBANTU :)
