Question 753700: Can you please help me solve the equation ?
I got as far as and now I am stuck. Found 2 solutions by stanbon, solver91311:Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! 3^(2x-4) +5=70
---
3^(2x-4) = 65
---
Take the log of both sides to get:
(2x-4)log(3) = log(65)
----
2x-4 = log(65)/log(3)
----
2x-4 = 3.7997
2x = 7.7997
x = 3.8998

You are stuck because you failed to take the log of the RHS when you took the log of the LHS. Furthermore, you didn't take the base 3 log of the LHS correctly.
Now use
Now use
From here, just solve for remembering that the log of a constant is just another numerical constant.
