PLease help i've totally forgotten how to do this i know it has something to do with the sequences of partial sums.

Show that (the sum from n=1-infinity) of 1/(2^(2n)) converges.

Sorry bout the crap way of writing it.

Hello,

Just use basic rules of exponents :

Hence

Is a convergent series ?

Hint : think geometric
