解log2(x^2-5x+8)=1
解方程log2(2-x)=log2(x-1)+1
解方程:log2(x+4)+log2(x-1)=1+log2(x+8)
解不等式:|log2(x-1)|+log2(5-x)
log2 (x + 3) + log2(x + 2) = 1
解不等式 log2(X平方+2X)>log2分之一(5-2X分之1)
解方程log2^(4^x+4)=x+log2^[2^(x+1)-3]
解方程log2(4^x+1)=x+log2(2^(x+3)-6)
解方程:log2(4^x+4)=x+log2(2^(x+1)-3)
解方程log2(x+14)-log2(x+6)=3-log2(x+2)
log2(x-2)=log4(5-x)
解方程log2(9x-1-5)=log2(3x-1-2)-2.
解方程:log2(9^(x-1)-5)-log2(3^x +2)-2=0
