Algebra Difficulty 1.9 Junior Find the answer

What is the value of 22014+220122201422012 ?\frac{2^{2014}+2^{2012}}{2^{2014}-2^{2012}} ?

Pick one

Solutions — 2

Solution 1

Factoring out, we get: 22012(22+1)22012(221)\frac{2^{2012}(2^2 + 1)}{2^{2012}(2^2-1)}.
Cancelling out the 220122^{2012} from the numerator and denominator, we see that it simplifies to (C) 53\boxed{\textbf{(C) }\frac{5}{3}}.

Solution 2

22014+220122201422012\frac{2^{2014}+2^{2012}}{2^{2014}-2^{2012}}
We can factor a 22012{2^{2012}} out of the numerator and denominator to obtain
22012(22+1)22012(221)\frac{2^{2012}*(2^2+1)}{2^{2012}*(2^2-1)}
The 22012{2^{2012}} cancels, so we get
(22+1)(221)=53\frac{(2^2+1)}{(2^2-1)}=\frac{5}{3}, which is CC
