Question

does \[\frac{1}{1-2x}=2^n\]?

Answer 1

not if x = 3!

Answer 2

what are the steps to get it from the left to the right?

Answer 3

apparently discrete math is my achilles heel lol

Answer 4

this question honestly does not make any sense. you have an x on one side and n on the other.

Answer 5

^^I agree.

Answer 6

hmmm..... well, i think i write it right..

Answer 7

should there be an 'n' up top instead of a 1?

Answer 8

Then I think they are not equal.

Answer 9

ooooooooooooohhhhhhhhh i bet i see what this should be. maybe.
\[\frac{1}{1-x}=\Sigma x^n\] for -1<x<1 now if we replace x by 2x we get
\[\frac{1}{1-2x}=\Sigma (2x)^n = \Sigma 2^nx^n\] for
\[-\frac{1}{2}<x<\frac{1}{2}\]
perhaps this is what you had in mind?

Answer 10

that looks more like it :)
