Math Help - Adding Exponent Variables

1. Adding Exponent Variables

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

Many thanks.

2. Re: Adding Exponent Variables

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

LaTeX hint: you can surround the superscript with curly braces if it consists of more than one symbol.

Yes that's correct.

4. Re: Adding Exponent Variables

Great. Thank you.
