log4 (x+2) = log2 (2x-1)
log2(x-2)=log4(5-x)
log4 (x+2) = log2 (2x-1)
解方程log4(2-x)=log2(x-1)-1
log4^(2-X)=log2^(X-1)-1
log4(log2^x)=log2(log4^x)求log2^x
解方程log2(2x)*log4(x/4)=2
求解log2 (3X+2)-log4 (X)=3
log2^x=log4^9
解方程log4(3*2^x+7)=log2(2^x+1)
解方程 log2(x^2-3)=2log4(6x-10)-1
1/2*log2(x+1)=log4(x+1) 这样子可以吗.
已知函数f(x)=log2(x/4)*log4(x/2)(2≤x≤4)
