Please assist me with the question below

7. (Chapter 15, Section 16.5) A particle moves from (0, 0, 0) to (3, 2, 1) under the influence of the vector field E( x, y, z ) = (32 24, 2xy24, 4xy2 23). (a) Show that the integral is independent of the path followed by using the Fundamental Theorem of Line Integrals (Theorem 16.5.1). (4) (b) Compute the integral i. by transforming the integral to an ordinary single integral (see Section 15.3) ii. using the Fundamental Theorem of Line Integrals. (7 )
