★ Given :-

$\hookrightarrow{ \sf{2x {y}^{4} - 5 {x}^{2} + {z}^{2} + xy}}$

Where,

→ x = 2

→ y = -1

→ z = -3

=====================

★ Solution :-

Put Values of x, y and z

======================

$\hookrightarrow{ \sf{2(2) { (- 1)}^{4} - 5 {(2)}^{2} + {( - 3)}^{2} + 2( - 1)}} \\ \\ \hookrightarrow{ \sf{4( { - 1)}^{4} - 5(4) + 9 - 2}} \\ \\ \hookrightarrow{ \sf{4 - 20 + 9 - 2}} \\ \\ \hookrightarrow{ \sf{ - 22 + 13}} \\ \\\hookrightarrow{ \sf{ - 9}}$
