Question

Es urgente, alguien me puede enseñar cómo se resuelve?

Answer 1

${(2x + 3y)}^{2} = 4 {x}^{2} + 12xy + 9 {y}^{2}$
${( {a}^{2} x + b {y}^{2}) }^{2} = {a}^{4} {x}^{2} + 2 {a}^{2} xb {y}^{2} + {b}^{2} {y}^{4}$
${(3 {a}^{3} + 8 {b}^{4} ) }^{2} = 9 {a}^{6} + 48 {a}^{3} {b}^{4} + 64 {b}^{8}$
${(4 {m}^{5} + 5 {n}^{6} ) }^{2} = 16 {m}^{10} + 40 {m}^{5} {n}^{6} + 25 {n}^{12}$
