log2 4+log2 (x+2)怎么算?

log2(4*-x+1)怎么等于log2(4*x+1)-2x log2^x*log2^2x=2 这个要怎么算?、 解不等式2log2 (x-4)< log2 (x-2) log2根号2怎么算? |2x-log2^x| 2(x+3)>3是怎么转换到log2[2(x+3)}>log2(3)的 log2^3*log3^4怎么算 1/2^(log2(12))怎么算? 解不等式Log2(4+3x-x^2)>log2(4x-2) 高一数学log2（4^x+4)=x+log2(2^(x+1)-3) log2(4^x+4)=x+log2(2^x+1-3) 解方程log2^(4^x+4)=x+log2^[2^(x+1)-3]
