Is there a way to prove this in upwards of 5 steps? Apparently there is??

Question

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.

Answer 1

A quantity of oxygen gas had 16.32 g of the radioactive isotope oxygen-19 in it. When measured exactly 10 minutes later, the amount of oxygen-19 was 0.964 g. What is the half-life, in seconds, of oxygen-19?

Answer 2

woops

Answer 3

let me repost this elsewhere

Answer 4

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