What if the problem is really 2^(x+2)+2^(x+1)=192 ?
If this is the case we have (2^x)(2^2)+(2^x)(2^1)=192
x=5(we don't need logs because we know 32 is a power of 2)
This problem is identical in form to the last one that you asked.
you have some:
To solve equations of these forms you must recognize that:
this allows you to re-express the original equation as:
factoring you get
Specifically, here you have k=2, and c=192, so:
