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

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 =
