Let 0 < a < 1 and f (x) = log logarithm with a as the base (a ^ 2x-2a ^ X-2), then f (x) < the value range of X X X

Let 0 < a < 1 and f (x) = log logarithm with a as the base (a ^ 2x-2a ^ X-2), then f (x) < the value range of X X X

F (x) is a logarithmic function of 0 < a < 1, let t = a ^ x, t is greater than 0
To make f (x) less than 0, so according to the image a ^ 2x-2a ^ X-2 is greater than 1, t = a ^ x is greater than 3
So the solution x is less than the logarithm of log with a as the base 3
