x + x?

y + y?

something + something?

This is what the expression

2

merely is. Once you get that, then you can use the appropriate property of exponents.

Oh I see, so it would be..

x + x?

y + y?

something + something?

This is what the expression

2^{k+1}+ 2^{k+1}

merely is. Once you get that, then you can use the appropriate property of exponents.

2*2

2

Not only does itOh I see, so it would be..

2*2^{k+1}= 2^{k+2}

and just another one for fun

2^{k+1}+2^{k+1}+2^{k+1}+2^{k+1}= 4*2^{k+1 }= 2*2*2^{k+1}= 2^{k+3}

Does this seem correct?
