is there a quicker more efficient way to solve this problem without actually adding?
2+2+2^2+2^3+2^4+...+2^8
answer choices:
2^9
2^10
2^35
2^37
2+2+2^2+2^3+2^4+...+2^8
answer choices:
2^9
2^10
2^35
2^37
2+2+2^2+2^3+2^4+2^5+2^6+2^7+2^8
4=2^2
2(2^2)+2^3....+2^8
2(2^3)+2^4....+2^8
If you start to recognize the pattern in this question, it's clear that the answer is 2(2^8) or 2^9.
