Question

Please show me how to simplify the following expression.
(2^n)-2^(n+1)
Thanks...

Answer 1

\[2^{n}-2^{n+1}=2^n-2\times 2^n\] is a start

Answer 2

then just like \(x-2x=-x\)
you have \(2^n-2\times 2^n=-2^n\)

Answer 3

for some reason my equation creator is not working and I also can not read what you just wrote....
it looks like this to me
\[2^{n}-2^{n+1}=2^n-2\times 2^n\]

Answer 4

i can read that perfectly
what do you see?

Answer 5

then just like \(x-2x=-x\) you have \(2^n-2\times 2^n=-2^n\)

Answer 6

try refreshing your browser, maybe you can see it
i see it, even when you wrote it

Answer 7

weird lol...ok ill restart the browser

Answer 8

just refresh, that might work
