oppppppppppppppppp euwuwiw

Answer 2

Answer:

Keep taking 2 common. 2(2^3–2^2–2–1)=2(2(2^2–2–1)-1)=2(2(2(2–1)-1)-1). Now solve from in to out.

Also (2^n) -1=sum of all powers of 2 from 0 to n-1.

This is what computers are based on loosely.

Alternately grouping the even powers and odd powers of two and then taking the common factors also gives the answer.

P.S. I love maths ;)
