SUMMARY
The logarithmic equation 9^x - 5*3^x + 6 = 0 can be solved by substituting y = 3^x, transforming the equation into a quadratic form: y^2 - 5y + 6 = 0. This quadratic can be factored easily, leading to the solutions for y. Once y is determined, the next step is to solve for x by reverting the substitution 3^x = y.
