How do I rearrange 3^(x+2) - 3^x = 1000000 to work out x. New to the forum so not sure how to type it but question is 3 to the power of (x+2) minus 3 to the power of x. I have even worked out an answer by trial and error of 10.682630385 but can't for the life of me see how to rearrange the equation (guessing there will be a log base 3 in there somewhere). Thanks David
