Question

√8 + √18 - √32 + √2=.. Rezolvarea!

Answer 1

2$\sqrt{2}$ +3$\sqrt{2}$ - 4$\sqrt{2}$ +$\sqrt{2}$ = 6$\sqrt{2}$ - 3$\sqrt{2}$ = 3$\sqrt{2}$

Answer 2

$\sqrt{8} + \sqrt{18} - \sqrt{32} + \sqrt{2} =2 \sqrt{2} +3 \sqrt{2} -4 \sqrt{2} + \sqrt{2} = \\ =5 \sqrt{2} -4 \sqrt{2} + \sqrt{2} = \sqrt{2} + \sqrt{2} =2 \sqrt{2}$
