Just a quick question. Is it correct to say that $\displaystyle 2^k+2^k=2^(^k^+^1^)$?

Many thanks.

Yes. $\displaystyle 2^k+2^k=2^k(1 + 1) = 2^k\cdot 2=2^{k+1}$.

LaTeX hint: you can surround the superscript with curly braces if it consists of more than one symbol. - Jul 2nd 2012, 05:54 AMGokuRe: Adding Exponent Variables
Yes that's correct.
