emulate xcas simplify integrate on hp prime g2

[Liamtoh Resu]

Is there a way on the prime to duplicate:

xcas: simplify(integrate(x^2,x,0,x)=1000)

to get the result:

(a^3)/3 = 1000

I can do translate the following xcas expression

fsolve(integrate(x^2,x,0,x)=1000)

to get

14.4224957031

which is an approximation for

10 * 3^(1/3)

Thanks.
