Answer:- 1

Explanation:-

Solution:

\begin{aligned} Given experssion , \\ \frac{a^{3} + b^{3} + c^{3} - 3 a b c}{a^{2} + b^{2} + c^{2} - a b - b c - c a} \\ = a + b + c \\ = 38 + 34 + 28 \\ = 100 \end{aligned}

$\eqalign{ & {\text{Given experssion ,}} \cr & \frac{{{a^3} + {b^3} + {c^3} - 3abc}}{{{a^2} + {b^2} + {c^2} - ab - bc - ca}} \cr & = a + b + c \cr & = 38 + 34 + 28 \cr & = 100 \cr}$
