(1)2根号2+|根号2-根号3|(2)(2根号2)-(3根号2)+(根号3)

(1)2根号2+|根号2-根号3|(2)(2根号2)-(3根号2)+(根号3)
(1)2根号2+|根号2-根号3|
(2)(2根号2)-(3根号2)+(根号3)

(1)2根号2+|根号2-根号3|(2)(2根号2)-(3根号2)+(根号3)
(1)2√2+|√2-√3|
=2√2+√3-√2
=√2-√3
(2)2√2-3√2-√3
=-2√2-√3

(1)2根号2+|根号2-根号3|
=2根号2+根号3-根号2
=根号3
(2)(2根号2)-(3根号2)+(根号3)
=2根号2-3根号2+根号3
=根号3-根号2

(1)2倍根号2+根号2-根号3
=3倍根号2-根号3
(2)2倍根号2-3倍根号2-根号3
=-根号2+根号3
=根号3+根号2
