XO is the solution of the equation a ^ x = loga x (0 〈 a 〈 1), then the size relationship of XO, 1, a is

XO is the solution of the equation a ^ x = loga x (0 〈 a 〈 1), then the size relationship of XO, 1, a is

The idea of tree combination
Draw the images of y = a ^ X and y = loga (x) respectively, and the abscissa of the intersection is XO
Because: 0
