Question

Упростите (2+3√2) • √((11-6√2)/2) + (√5+3)/(√5-1)^-2

Answer 1

$( sqrt{2} +3)* sqrt{ (3- sqrt{2}) ^{2} } +( sqrt{5} +3)*(6-2 sqrt{5})$$( sqrt{2} +3)*(3- sqrt{2} )+2 *( sqrt{5} +3)*(3- sqrt{5} )$$9-4+2*(9-5)=5+2*4=13$$frac{2+3 sqrt{2} }{ sqrt{2} } * sqrt{9-6 sqrt{2}+2 } +( sqrt{5} +3) ( sqrt{5}-1 )^{2}$
