**Matt Eaton**, Monday, February 18, 2008 at 9:14pmsorry, the x in between 6 and three is multiplication... so it should be

3^2x - 6(3^x) + 9 = 0

**Reiny**, Monday, February 18, 2008 at 9:22pmI am going to rewrite the equation for you

(3^{x})^{2}- 6(3^{x}) + 9 = 0

there is a strong hint there.

(3^x - 3)^2 = 0
