Question

(20 raiz de 10+10 raiz de 18) /2 raiz de 2

Answer 1

$\frac{20 \sqrt{10}+10 \sqrt{18} }{2 \sqrt{2} } \\ \\ \frac{20. \sqrt{5.2}+10 \sqrt{9.2} }{2 \sqrt{2} } \\ \\ \frac{20 \sqrt{5}. \sqrt{2}+10 \sqrt{9}. \sqrt{2} }{2 \sqrt{2} } \\ \\ \frac{20. \sqrt{5}. \sqrt{2}+10.3. \sqrt{2} }{2 \sqrt{2} } \\ \\ \frac{20 \sqrt{5}. \sqrt{2}+30 \sqrt{2} }{2 \sqrt{2} } \\ \\ \frac{2 \sqrt{2}(10 \sqrt{5}+15 ) }{2 \sqrt{2} } \\ \\ 10 \sqrt{5} +15$
