I am supposed to do corrections for this question but I do not know how.
The correct answer is
Here are the steps I have done:
so you can think of as a quadratic equation for . As Unknown008 (who is that masked man?) suggested, let and you get . Solve that quadratic equation for y and then solve for p.
Any help would really be appreciated, thank you very much in advance!
at this point either p or 2-p have to be 0, since the difference of 2 powers of 2 give an odd number only if the power of one is 0. also p cannot be zero since then 2-p=2 which gives -3.
