    it will convert into the integral of (x/x +2sqrtx/x+1/x) then simplize it into integral of (1+2/sqrtx + 1/x) so integrate: int(1)=x int(2/sqrtx)=2sqrtx int(1/x)=ln x result : x+2sqrtx + lnx

    \[\int\limits 1{}^{?}\] = 1 \[\int\limits 2/\sqrt{x} {?}^{?}\]=\[2\sqrt{x}\] \[\int\limits1/x{?}^{?}\]=\[\ln x\]
