Question

√32+√98-√50

____________  x √8 = ... 

√72

Answer 1

(4sqrt(2)+7sqrt(2)-5sqrt(2))/6sqrt(2)*2sqrt(2)=6sqrt(2)/6sqrt(2)*2sqrt(2)=2sqrt(2)

Answer 2

$frac{sqrt{32}+sqrt{98}-sqrt{50}}{sqrt{72}}*sqrt{8}=frac{sqrt{16*2}+sqrt{49*2}-sqrt{25*2}}{sqrt{2*36}}*sqrt{2*4}=\=frac{4sqrt{2}+7sqrt{2}-5sqrt{2}}{6sqrt{2}}*2sqrt{2}=frac{6sqrt{2}}{6sqrt{2}}*2sqrt{2}=2sqrt{2}$
