2

Take the square of the first term: $7m^2$

$49m^{4}$
3

Twice ($2$) the product of the two terms: $7m^2$ and $8n^4$

$112m^2n^4$
4

Take the square of the second term: $8n^4$

$64n^{8}$
5

Add the three results, and we obtain the expanded polynomial

$49m^{4}+112m^2n^4+64n^{8}$

Final answer to the exercise

$49m^{4}+112m^2n^4+64n^{8}$
