Line integral of a vector field along a curve C with two segments

Vector field $ vec F = (3x^2y^3+8x)vec i + 3x^3y^2vec j$, along a curve C consisting of two segments C$_1$ and C$_2$.



Line segment C$_1$ given by $y = 0$ and $0 ≤ x ≤ x_0$ and the line segment C$_2$ given by $x = x_0$ and $0 ≤ y ≤ y_0$.



I need help calculating the line integral of:



$V(x_0,y_0) = int_0vec F cdot dvec r = int_C ((3x^2y^3+8x)dx + 3x^3y^2dy) $



The boundaries in the segments really throw me off, any help would be very much appreciated.



Thank you very much!

hint



along $C_1 , dy=0$ gives



$$I_1=8int_0^{x_0}xdx=4x_0^2$$



along $C_2, dx=0$ and



$$I_2=3x_0^3int_0^{y_0}y^2dy=x_0^3y_0^3$$



the result is $$I=I_1+I_2$$
