How can I express the equation

$c = 2^{m+1} - 2^m$

in terms of m? t.i.a.

It already seems to be expressed in terms of $m$. Please clarify what you want. – Henning Makholm Sep 14 '11 at 22:11

What do you means by write in term of $m$? Do you means simplify? Do you mean any of the following?

$c = 2^{m}(2 - 1) = 2^{m}(1) = 2^m$

or $m = log_2 c$.

If you are asking the OP for clarification, please do so in the comments. – Austin Mohr Sep 14 '11 at 22:09
    
I'd be surprised if OP meant anything other than "solve for $m$ in terms of $c$," and in that context this qualifies as an answer. – Gerry Myerson Sep 14 '11 at 22:28
