=(2√2.4)+(√9.2)+(1/4√16.2)+(√100.2)
=(2.2√2)+(3√2)+(1/4.4√2)+(10√2)
=4√2 + 3√2 + √2 + 10√2
=17√2

2 . 2  \sqrt{2} +  3\sqrt{2} +  \frac{1}{4} . 4 \sqrt{2} + 10 \sqrt{2}  \\ 4 \sqrt{2} +3 \sqrt{2} + \sqrt{2} +10 \sqrt{2}  \\ 18 \sqrt{2}
kok bisa hasilnya 18 √ 2 bisa dijelasin gak?
4 + 3 + 1 + 10 (akar 2)
makasih ya :)
