OK so i'm having trouble with two problems.

first off

$\displaystyle \int_{0}^{2} \frac{1}{\sqrt{l x-1 l}} dx$

i know to split into two limits but i don't know what to do with the square root.

second

$\displaystyle \int_{0}^{1} \frac{1}{2 \sqrt{x}} dx$

this one i don't really know where to start

any help would be appreciated, Thanks
