Question

$(sqrt{29*12sqrt{5} } -sqrt{29+12sqrt{5} } )^{2}$

Answer 1

$(sqrt{29-12sqrt{5} } -sqrt{29+12sqrt{5} })^{2}=(sqrt{9-12sqrt{5} +20} - sqrt{9+12sqrt{5} +20})^{2}=(sqrt{(3-2sqrt{5})^{2} } -sqrt{(3+2sqrt{5} )^{2} })^{2}=(|3-2sqrt{5}|-|3+2sqrt{5}|)^{2}=(2sqrt{5}-3-3-2sqrt{5})^{2}=(-6)^{2}=36$

Answer 2

первый корень 29*12√5?
да, все верно
