Hi all

We have our maths exam on tuesday and I am doing revision and there is a question on this sheet we have that I can't figure out the process of answering it for.

I have to find x, and I figured it out by guess + checking on the calculator, but how do I do it algebraically?

$\displaystyle 4^x+3*4^x=1$

What is the steps needed to find the answer?

Any help is appreciated

EDIT:

Nevermind I got it ended up being something simple which I overlooked...

I forgot that $\displaystyle 4^x+3*4^x=4*4^x$ so I understood it and divided both sides by 4, and then went from there
