Is there a way to prove this in upwards of 5 steps? Apparently there is??
Prove.
2^n + 2^n = 2^(n+1)
I posted this before however apparently I need something more indepth in terms of the # of steps.

A quantity of oxygen gas had 16.32 g of the radioactive isotope oxygen19 in it. When measured exactly 10 minutes later, the amount of oxygen19 was 0.964 g. What is the halflife, in seconds, of oxygen19?

woops

let me repost this elsewhere

LS = 2^n + 2^n
= 2(2^n)
= 2(n+1)
= RS
