2次根式计算(√48-3√2)(√18+4√3)-(√3-√2)^21.(√48-3√2)(√18+4√3)-(√3-√2)^22.1/3√2+(√3+√2)/√6-(3√1/2-√3)
1.(√48-3√2)(√18+4√3)-(√3-√2)^2
=(4√3-3√2)(3√2+4√3)-(√3-√2)^2
=(48-18)-(5-2√6)
=30-5+2√6
=25+2√6
2.1/3√2+(√3+√2)/√6-(3√1/2-√3)
=√2/6+(3√2+2√3)/6-3√2/2+√3
=2√2/3+√3/3--3√2/2+√3
=-5√2/6+4√3/3

1.(√48-3√2)(√18+4√3)-(√3-√2)^2
=(4√3-3√2)(3√2+4√3)-(3-2√6+2)
=48-18-5+2√6
=25+2√6
2.1/3√2+(√3+√2)/√6-(3√1/2-√3)
=1/3√2+(3√2+2√3)/6-(3/2√2-√3)
=1/3√2+1/2√2+1/3√3-3/2√2+√3
=4/3√3-2/3√2
