SOLUTION: 1. Solve the following equations a) 9^(x)- 5(3^x) +6 =0 (hint let y = 3^x) Can you please help me out? Thanks so much in advance:) Can you please show all the steps it would

Question 744700: 1. Solve the following equations
a) 9^(x)- 5(3^x) +6 =0 (hint let y = 3^x)
Can you please help me out? Thanks so much in advance:)
Can you please show all the steps it would really help me understand:)

Answer by josgarithmetic(39620) (Show Source): You can put this solution on YOUR website!
9^(x)- 5(3^x) +6 =0 (hint let y = 3^x)

, There is a rule of exponents for that.
Your hinted substitution:
, which is factorable into....

Either y=2 OR y=3
Reversing the substitution done,
Either Or

Whatever base you want, find logarithms of both sides for each choice of solution.

, I skipped a step. You might want that as

Do similarly for the other choice.
