Answer 1

$81 {a}^{2} b ^{4} \: - \: 36ab ^{2} \: + \: 4$

${9}^{2} {a}^{2} {b}^{2 \: \times \: 2} \: - \: 2 \: \times \: {9ab}^{2} \: \times \: 2 \: + \: {2}^{2}$

${9}^{2} {a}^{2} \: \times \: (b^{2} ) ^{2} \: - \: 2 \: \times \: {9ab}^{2} \: \times \: 2 \: + \: {2}^{2}$

$(9 {ab}^{2} ) ^{2} \: - \: 2 \: \times \: {9ab}^{2} \: \times \: 2 \: + \: {2}^{2}$

$\boxed{ \bold{( {9ab}^{2} \: - \: 2) ^{2} }}$
