计算:(1)3根号(2)-2根号(12)-4根号(1/8)+3根号48 急!
=3√2-2×2√3-4×√2/4+3×4√3
=3√2-4√3-√2+12√3
=2√2+8√3;
(2)(根号3-1)²-(1/2)-1次方+4/根号(3)+1+(1-根号2)的0次方
=3+1-2√3-2+2(√3-1)+1
=4-2√3-2+2√3-2+1
=1;
(3)a/b根号(a²b)*2根号(b²/a)÷2/3根号a³b
=(a/b×2×(3/2))×√(a²b×b²/a×1/a³b)
=(3a/b)(b/a)
=3;
(4)根号(a²b)+a根号(b/a)-b根号a/b-根号ab²
=4a√b+√ab-√ab-b√a
=4a√b-b√a;
