4. ### Power Series. Calc 2 help! Best answer awarded asap :) Thank you!?

2x/(9 + x) = 2x/(9 * (1 + x/9)) = (2x/9) * 1/(1 - (-x/9)) = (2x/9) Σ(n = 0 to ∞) (-x/9)^n, via geometric series = Σ(n = 0 to ∞) 2 * (-x/9)^(n+1) = 0 - (2/9)x + (2/ 81 )x^2 - (2/729)x^3 + (2/9^4)x^4 - (2/9^5)x^5 + ... I hope this helps!
