Question

Care este răspunsul?

Answer 1

$\frac{5(3 \sqrt{5} + 2 \sqrt{11}) }{3 \sqrt{5} + 2 \sqrt{11} } \times \frac{2 \sqrt{6} }{3 \times 2} = \\ = 5 \times \frac{ \sqrt{6} }{3} \\ = \frac{5 \sqrt{6} }{3}$

Answer 2

5(3√5+2√11)/3√5+2√11 = 2√6/3*2 =

= 5*2√6/3*2 = 

= 5*√6/3 = 5√6/3

se  simplifica 3√5 +2√11 cu 3√5+2√11 apoi  2 cu 2.
