$\bf\green{\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: Resolvemos:}$

$(2m {n}^{2} - 3 {)}^{2}$

$(2m {n}^{2} {)}^{2} - 2 \times 2m {n}^{2} \times 3 + {3}^{2}$

$\boxed{4 {m}^{2} {n}^{4} - 12m {n}^{2} + 9 }$

Answer 2

$(2mn {}^{2} - 3) {}^{3} = \\ (2mn {}^{2} ) {}^{3} - 3(2mn {}^{2} ) {}^{2} (3) + 3(2mn {}^{2} )(3) {}^{2} - (3) {}^{3} \\ 8m {}^{3} n {}^{6} - 3(4m {}^{2} n {}^{4} )(3) + 3(2mn {}^{2} )(9) - (27) \\ 8m {}^{3} n {}^{6} - 36m {}^{2} n {}^{4 } + 54mn { }^{2} - 27$
