Answer 2

Hey buddy!!

Here is yr answer.....

$given \\ m = 5 \: \\ n = 8 \\ \\ = > \frac{4}{25}m^{2} - mn + { \frac{25}{16} }n^{2} \\ \\ = > \frac{4}{25} \times 5^{2} - (5)(8) + { \frac{25}{16} } \times 8^{2} \\ \\ = > \frac{4}{25} \times 25 - 40 + \frac{25}{16} \times 64 \\ \\ = > 4 - 40 + 100 \\ \\ = > 104 - 40 \\ \\ = > 64$

Hope it hlpz.....
