ok so for here $$\large{\sum _{i=1}^{10}} 2^i$$

fibonaccichick666 · Answer

so, let's discuss first

fibonaccichick666 · Answer

can you tell me what the value of $2^i=?$ when i=1?

anonymous · Answer

So that would make it 2^1 or just 2 correct @FibonacciChick666?

fibonaccichick666 · Answer

sorry for the delay, yes

fibonaccichick666 · Answer

how about when i=2?

anonymous · Answer

I'm sorry. 2^2 would be 4 @FibonacciChick666

fibonaccichick666 · Answer

yep, so now do that for all the numbers to ten and just add them all together

fibonaccichick666 · Answer

that's all there is to it :)

anonymous · Answer

So like 2^1-10 or 1-10^1-10? (if that makes sense) @FibonacciChick666 (- means through)

fibonaccichick666 · Answer

the first one.  just like we did, we just plug in the i values 1,2,3...,10 then add the resulting values togehter
