sederhanakanlah ! 4√50+7√18-2√2=

[tex]4 \sqrt{50} + 7 \sqrt{18} - 2 \sqrt{2} \\ = 4 \sqrt{25 \times 2} + 7 \sqrt{9 \times 2} - 2 \sqrt{2} \\ = 4 \times 5 \sqrt{2} + 7 \times 3 \sqrt{2} - 2 \sqrt{2} \\ = 20 \sqrt{2} + 21 \sqrt{2} - 2 \sqrt{2} \\ = 39 \sqrt{2} [/tex]

4 akar(50) + 7 akar(18) - 2 akar(2)
= 4 akar(25 . 2) + 7 akar(9 . 2) - 2 akar(2)
= 4 . 5 akar(2) + 7 . 3 akar(2) - 2 akar(2)
= 20 akar(2) + 21 akar(2) - 2 akar(2)
= 39 akar(2)

Semoga membantu :)
