2的负1次方×的次方＋lg2×lg2500＋2（lg5)－4的log次方＋log(log(lg(lne))) =1/2*4^(3*2/3)+lg2*(lg25*100)+2(lg5)^2-2^(2*log2*3)+log2 (log3 lg 1000) =1/2*4^2+lg2*(lg25+lg100)+2(lg5)^2-[2^(log2 3)]^2+log2 (log3 3) =8+lg2*(2lg5+2)+2(lg5)^2-3^2+log2 1 =8+2lg2*lg5+2lg2+2(lg5 )^2 -9+0 =-1+2lg2*lg5+2lg2+2(lg5 )^2 =-1+2lg5*(lg2+lg5)+2lg2 =-1+2lg5*lg10+2lg2 =-1+2lg5+2lg2 =-1+2(lg5+lg2) =-1+2lg10 =1
