Question

VA rog pas cu pas nu pe calculator dau pls până la 20:00 va implor. ​

Answer 1

$\frac{8 \sqrt{2} }{ \sqrt{27} } + \frac{7}{ \sqrt{6} } - \frac{6 \sqrt{3} }{ \sqrt{8} } + \frac{5 \sqrt{2} }{3 \sqrt{3} } = \frac{8 \sqrt{2} }{3 \sqrt{3} } + \frac{7}{ \sqrt{2} \times \sqrt{3} } - \frac{6 \sqrt{3} }{2 \sqrt{2} } + \frac{5 \sqrt{2} }{3 \sqrt{3} } = \frac{8 \sqrt{2} \times 2 \sqrt{2 } + 7 \times 6 - 6 \sqrt{3} \times 3\sqrt{3} + 5 \sqrt{2} \times 2 \sqrt{2} }{6 \sqrt{6} } = \frac{32 + 42 - 54 + 20}{6 \sqrt{6} } = \frac{40}{6 \sqrt{6} } = \frac{40 \sqrt{6} }{36} = \frac{10 \sqrt{6} }{9}$
