Answer 1

a.

$(3m - 4)(3m + 4)$

$(3m {)}^{2} - {4}^{2}$

${9m}^{2} - {4}^{2}$

${9m}^{2} - 16$

La respuesta es: 9m² - 16

b.

$( {a}^{3} {)}^{2} - ( {b}^{3} {)}^{2}$

${a}^{6} - ( {b}^{3} {)}^{2}$

${a}^{6} - {b}^{6}$

la respuesta es a⁶ - b⁶

c.

$( \frac{3}{5} {m}^{2} n - \frac{1}{2} {n}^{3} )( \frac{3}{5} {m}^{2} n + \frac{1}{2} {n}^{3} )$

$( \frac{3}{5} {m}^{2} n {)}^{2} - ( \frac{1}{2} {n}^{3} {)}^{2}$

$\frac{9}{25} {m}^{4} {n}^{2} - ( \frac{1}{2} {n}^{3} )$

$\frac{9}{25} {m}^{4} {n}^{2} - \frac{1}{4} {n}^{6}$
