=(x(x-1))/2

Explanation:

.

(x^2(x^2-2x+1)lne^xsin(pi/4))/((x^(-1))^(-1)e^lnx(x-1)sqrt2)

lne^x=xlne=x

sin(pi/4)=sqrt2/2

(x^(-1))^(-1)=x^((-1)(-1))=x^(+1)=x

e^lnx=x

(x^2-2x+1)=(x-1)^2

Let's substitute all of them:

(x^2(x^2-2x+1)lne^xsin(pi/4))/((x^(-1))^(-1)e^lnx(x-1)sqrt2)=

(x^2(x-1)^2xsqrt2/2)/(x*x(x-1)sqrt2)=(x-1)x(1/2)=(x(x-1))/2
