 P: 79 This is a really basic problem and I just need some review. How do I add 2k+1 + 2k+1? This is where I am stuck 212k+212k
 HW Helper P: 1,347 Think of it this way. Can you add x + x? y + y? something + something? This is what the expression 2k+1 + 2k+1 merely is. Once you get that, then you can use the appropriate property of exponents.

Oh I see, so it would be..

2*2k+1 = 2k+2

and just another one for fun

2k+1+2k+1+2k+1+2k+1 = 4*2k+1 = 2*2*2k+1 = 2k+3

Does this seem correct?
