The problem is in the beginning. Because if you take the logarithm of the two sides then the equation becomes:

$\displaystyle \log(y)=\log(5\cdot 2^x+8)$

But there's no rule for $\displaystyle \log(a+b)=...?$. - Sep 13th 2011, 06:12 PMVeronica1999Re: linearizing log equations
Then how can the difficulty be avoided?
