Help - taking the test tomorrow

Post Wed Nov 01, 2006 4:13 pm
HI I need help on a math question
Can someone help me figure out if there is a formula for solving this?

2^1+2^1+2^2+2^3+2^4+2^5+2^6+2^7+2^8+2^9 = ???

The answer is 2^10 or 1024

2^1*2+2^2+2^3+2^4+2^5+2^6+2^7+2^8+2^9 =

2^2+2^2+2^3+2^4+2^5+2^6+2^7+2^8+2^9 =

2^9+2^9
2*2^9
=2^10

Hope this helps!
