计算2^(1+1/2log2 5)+(lg5)^2+lg2lg50

计算：（1）log2 (4^3*8^5);(2)log2 3+log2 6-log2 9 计算 根号下[(log2 5)^2-4log2 5+4]+log2 1/5 计算log2 √(48/7)-log2 12+(1/2)log2 42-1 计算(log3 2)(log2 6-1) 计算2^(1+1/2log2 5)+(lg5)^2+lg2lg50 计算：9^[log3(2)]-2[1+0.5log2(5)] [log2 1]+[log2 2]+[log2 3]+[log2 4]+[log2 5]+...+[log2 1024]=?[x]表示不超过x的最大整数2为底 答案是8204 计算log2.5（6.25）+lg1/100+In根号下e+2[1+log2(3)]2.5是下标,[1+log2(3)]是上标,(3)是上标 log2 SQR(7/48)+log2 12 -1/2log2 42 log2 SQR(7/48)+log2 12 -1/2log2 48 解2log2^(x-5)=log2^(x-1)+1 求值：log2 (5/56)^(1/2)+log2 (14)-(1/2)log2 (35)=log2中2为底数=1/2[-2log2 (7)-3]+log2 (2)+log2 (7) 中的1/2[-2log2 (7)-3]是怎么得到的？ 4^1/2（log2^9-log2^5）的值 , |[log2(x)]^2-3log2(x)+1| (log2)2+log2*log50+1g25值 计算log2 1/4+2^log2 2+91lg1+(0.25)^(1/2)×(-1/27)^(-2/3). 计算 log2（1+√2+√3）+log2（1+√2+√3) 计算(log3(2))*(log2(6-1))=?__________尤其是(log2(6-1))=?
