Question

(Radical 98-2radical50+radical32):1supra radical 2 cum se calculează?

Answer 1

$(\sqrt{98} - 2 \sqrt{50} + \sqrt{32}) \div \frac{1}{ \sqrt{2} } = (7 \sqrt{2} - 2 \sqrt{50} + 4 \sqrt{2} ) \div \frac{1}{ \sqrt{2} } = (11 \sqrt{2} - 2 \sqrt{50} ) \div \frac{1}{ \sqrt{2} } = (11 \sqrt{2} - 10 \sqrt{2} ) \div \sqrt{2} = \sqrt{2} \times \sqrt{2} = \sqrt{4} = 2$
