Question

CAN ANY ONE ANSWER THE E NUMBER​

Answer 1

Step-by-step explanation:

$L.H.S = (a^{2}+b^{2} )^{2} -2 a^{2} b^{2} \\= [(a^{2})^{2} + (b^{2})^{2} + 2 (a^{2} )(b^{2} )] - 2 a^{2} b^{2} \\ (since (x+y)^2=x^{2}+y^{2} +2xy)\\= a^{4}+b^{4}+ 2 a^{2} b^{2} - 2 a^{2} b^{2} \\= a^{4}+b^{4} = R.H.S$
