(5+根号6)(5根号2-2根号3)
(5+根号6)(5根号2-2根号3) (5+根号6)(5根号2-2根号3)
=5*5根号2-5*2根号3+根号6*5根号2-根号6*2根号3
=25根号2-10根号3 +5根号12-2根号18
=25根号2-10根号3+5根号下4*3-2根号下9*2
=25根号2-10根号3+10根号3-6根号2
=19根号2
望采纳,谢谢!
(5+√6)(5√2-2√3)=25√2-10√3+5√12-2√18=25√2-10√3+10√3-6√2=19√2
(5+根号6)(5根号2-2根号3)
=25根号2-10根号3+5根号12-2根号18
=25根号2-10根号3+10根号3-6根号2
=19根号2
