Question

x^4+y^4 how to solve using identities​

Answer 1

Answer:

Here is the answer =>

Step-by-step explanation:

Equation =>x^4+y^4

=>x^4+y^2

=>(x^2)^2+(y^2)^2

=>(x^2+y^2)^2-2x^2y^2.

☆As (a^2+b^2)=(a+b)^2-2ab.

☞So (x^2+y^2)^2-2(xy)^2 is the required answer.

HOPE IT HELPS.

Answer 2

Step-by-step explanation:

x^4+y^4

(x^2+y^2)(x+y)(x+y)

since formula a^2+b^2= (a +b) (a+b) can be applied here

x^4+y^4

(x^2)^2+(y^2)^2

(x^2+y^2) (x^2+y^2)

(x^2+y^2) (x+y) (x+y)
