a^4+b^4= [a²]²+[b²]²
use identity
[a+b]²=a²+b²+2ab
transport 2ab to L.H.S side
we get as follows
[a+b]²-2ab=a²+b²--------[1]
then a=a²
b=b²
substitute in equation [1]
we get as follows
a²+b²=[a+b]²-2ab
[a²]²+[b²]²=[a²+b²]²-2a²b²
a^4+b^4=[a²+b²]²-2a²b²
use identity
[a+b]²=a²+b²+2ab
transport 2ab to L.H.S side
we get as follows
[a+b]²-2ab=a²+b²--------[1]
then a=a²
b=b²
substitute in equation [1]
we get as follows
a²+b²=[a+b]²-2ab
[a²]²+[b²]²=[a²+b²]²-2a²b²
a^4+b^4=[a²+b²]²-2a²b²
