Solve what??

2. anonymous

$\sum_{0}^{\infty}(1/2)^{n}$

i believe you can use sum of geometric series formula $\frac{a(1-r ^{n})}{1-r}$ a= first term r = 1/2

4. dumbcow

r^n = r^inf = 0

5. anonymous

$\int\limits \sqrt{1+e^{x}}$

6. dumbcow

hmm im not sure on this one how are you approaching this?
