Answer 1

12 000 / (350√2) × (√2/√2)

12000√2 / 350√4

12000√2 / 350(2)

12000√2 / 700

120√2/7

Answer 2

$\frac{1200}{(350 \sqrt{2} )} = \frac{24}{7 \sqrt{2} } = \frac{24}{7 \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{24 \sqrt{2} }{7 \sqrt{2} \sqrt{2} } \\ = \frac{24 \sqrt{2} }{7 \times 2} = \frac{24 \sqrt{2} }{14} = \frac{12 \sqrt{2} }{7}$
