Answer 1

Answer:

$(a) \: \frac{16}{81} {m}^{2} - 121 \\ = { (\frac{4}{9}m) }^{2} - ( {11)}^{2} \\ = ( \frac{4}{9} m + 11)( \frac{4}{9} m - 11)$

$(b)64 {a}^{6} - 49 {b}^{2} {c}^{4} \\ = {(8 {a}^{3} )}^{2} - {(7b {c}^{2}) }^{2} \\ = (8 {a}^{3} + 7b {c}^{2} )(8 {a}^{3} - 7b {c}^{2} )$

$(c) {x}^{2} - 0.01 \\ = {(x)}^{2} - {(0.1)}^{2} \\ = (x + 0.1)(x - 0.1)$
