1. (ii) Solve the equation

4^x-3(2^(x+1))=0

So what I did is

(2^x)^2-6(2^x)=0

2^x(2^x-6)=0

-2^x | 6

How do I go on from here?
2. Right idea but something went awry at the end of your solution.

This is all good. Now solve.

We last had this question a couple of days ago.

Here it is.

Cheers, I didn't realise that I have to equal 2^x=6. Got the solution.
