Question 1109820: solve 3(2^2x+3)-5(2^x+2)-156=0
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! solve 3(2^2x+3)-5(2^x+2)-156=0
---
You need to put more parentheses in your post.
3(2^2x+3) can be interpreted in more than one way::
3(2^2x+3) = 3(2^(2x+3))
OR
3(2^2x+3) = 3*2^2x + 3*3 = 3*2^(2x) + 9
----
Which is correct?
