Remember that , so you could rewrite like this:
Can you take it from here?
Regarding the second,
Can you take it from here?
I'm basically done all the questions that I needed to do, yet this one I can't seem to find how to answer for some reason.
3(2)^x = 4^(x + 1)
To find x, I try to put it to logarithmic function,
3*(x)(Log 2) = (x + 1)(Log 4)
My question is, is that where the 3 goes? It multiplies (x)(Log 2)? Doing it this way I end up with,
0.9x - 0.6x = 0.6
x = 2
The correct answer however is -0.42
I really need help what to do with that 3, as I've read the book plenty now and I still don't know how this works! Please help!
There's also another question similar to this, and of course I can't answer it either.
5(4)^2x = 4(2)^6x
Any help is greatly appreciated!
