Hi, I've tried to solve this equation, but I got the wrong answer. Could anymore kindly explain to me how to solve it? Find the exact solution of the equation 9^2x = 27^(i-x). Thanks, Amine.

Find the exact solution of the equation 9^2x = 27^(i-x). Thanks, Amine. $\displaystyle 9 = 3^2$ and $\displaystyle 27 = 3^3$ So you have $\displaystyle 3^{2(2x)} = 3^{3(i - x)}$.
Thanks a lot!
