0.3^2,2^0.3,log2(0.3) 怎么比较大小用什么方法

0.3的2次方与log2的0.5比较大小 指对数比较大小问题(1）2^0.3,0.3^2,log2 0.3;(2)log1/2 0.4,lg0.4,log2 0.4;(3)当1 比较log2（0.3）与log1/2（3）和lg1/2与log2（1/2）这两对分别得大小请把过程详写. log2 SQR(7/48)+log2 12 -1/2log2 42 log2 SQR(7/48)+log2 12 -1/2log2 48 log2^(4^7*2^5)+log2^6-log2^3 (log2 9)/(log2 8) = 2/3(log2 3) log2 3乘以log2 3等于2log2 (log2)^2+(log5)^2+log2*log25 |[log2(x)]^2-3log2(x)+1| 化简：(log2(x/4))*(log2(x/2)) 2log2 10—log2 25=? (log2)2+log2*log50+1g25值 log2 50-2log2 5 等于多少? [log2]2+log2乘log50+log25 log2 0.3 和0.3^2 和2^0.3怎么比较大小 0.3^2,2^0.3,log2 0.3这三个数之间的大小顺序是 0.3^2,log2^0.3,2^0.3 这三个书的大小顺序是
