Question

Consider the function u:R3→R given by
$u(x_1,x_2,x_3)=x_1x^4_2x^2_3-x^3_1x^4_3-26x^2_1x^2_2x^3_3$
Let CεN be such that
$x_1\frac{ ∂u}{∂x_2}+2x_2\frac{ ∂u}{∂x_3}$
evaluate at the point (t, t2,t3), eqals ctk for every tεR, The n the value of K is equal to____.

Answer 1

The correct answer is:14
