We just started logarithms and exponential functions, and I'm kind of getting the gist but not really. Here is what I tried on one of the homework problems:

3)0=1 or no solutions

I wasn't sure what to do between steps 1 and 2. Thanks!!

    If the question is the way you typed it, it is a nasty question.
    I am pretty sure you meant
    2^x = 4^(x+1)

    did you notice that both bases are powers of 2 ?
    2^x = (2^2)^(x+1)
    2^x = 2^(2x+2)
    then 2x + 2 = x
    x = -2

    I see where the extra step was! Thanks so much!
