(1)2又1/5*(1/3-1/2)*3/11/1又1/3
=11/5*(-1/6)*3/11*3/4
=-11/30*3/11*3/4
=-1/10*3/4
=-3/40
(2)cos45*(-1/2)^-2-(2倍的根号2-根号3)^0+根号32的绝对值+1/根号2
=1/2√2*4-1+4√2+1/2√2
=2√2-1+4√2+1/2√2
=13/2√2-1
2又1/5*(1/3-1/2)*3/11/1又1/3
=11/5*(1/3-1/2)*3/11/(4/3)
=3/5*(1/3-1/2)/(4/3)
=3/5*3/4*(2/6-3/6)
=9/20*(-1/6)
=-3/40
cos45°*(-1/2)^(-2)-(2√2-√3)^0+√32
=√2/2*(-2)^2-1+4√2
=√2/2*4-1+4√2
=2√2-1+4√2
=6√2-1
