(x^4+y^4)(x^2+y^2)

Question

i am 5th standerd student

Answer 1

(x^4 +y^4)*(x^2+y^2)

=x^6+x^2*y^4 +x^4y^2 +y^6

Answer 2

If you mean x^4, or x to the 4th power , when you write x4, then none of the answers make sense, since x^4 + y^4 cannot be factored. 

 

If x^4 - y^4 is in fact intended, then the answer is A,

since x^4 - y^4 = (x^2 + y^2)(x^2 - y^2). So,

 

x2 + y2

=(x^4 - y^4) / (x^2 - y^2) 

=[(x^2 + y^2)(x^2 - y^2)] / (x^2 - y^2) 

x^2 + y^2
