${(x^{2} + y^{2})}^{3} = 4 a^{2} x^{2} y^{2}$
${(x^{2} - y^{2})}^{3} = 4 a^{2} x^{2} y^{2}$
${(x^{2} + y^{2})}^{3} = 2 a^{2} x^{2} y^{2}$
${(x^{2} - y^{2})}^{3} = 2 a^{2} x^{2} y^{2}$

Answer:The correct answer is: $open parentheses x to the power of 2 end exponent plus y to the power of 2 end exponent close parentheses to the power of 3 end exponent equals 4 a to the power of 2 end exponent x to the power of 2 end exponent y to the power of 2 end exponent$
