27^(2/3) - 2^log2(3) × log2(1/8) + 2lg(√3+√5+√3-√5)的结果 两个5都是
27^2/3-2^log2^3xlog2^1/8+lg^4+2lg^5等于
log2(√1/48)+log2 12-1/2log2 (24)-1/3
计算:lg(1/2)-lg(5/8)+lg(12.5)+log2为底3*log3为底8=
log2 3/log2 5等于log2 3-log2 5么?
(log2 9)/(log2 8) = 2/3(log2 3)
log2(20)-log2(5)+2log3(2)×log4(3)
log的计算 :log2(20)-log4(25)= log3(2)×log2(5)×log5(3)=?log2[log
不等式log2(2x+3)>log2(x+1)的解集是
2^log2 (3) × log2 (1/8) + 2lg3
log2 3乘以log2 3等于2log2
比较log2 √2与log2 √3,log3 2与1,log1\3 4与0的大小
(log2^3 +log3^5) x ( log3^5 +log9^5 ) x lg 2 ,
