Answer 1

hey!

Answer:

a^4+b^4+c^4+2a^2*2b^2+2b^2+2c^2+2c^2+2a^2

Step-by-step explanation:

a^4+b^4+c^4= (a^2+b^2+c^2)^2

now, use identity (a+b+c)^2= a^2+b^2+c^2+2ab+2bc+2ca

= (a^2)^2+(b^2)^2+(c^2)^2+2(a^2)(b^2)+2(b^2)(c^2)+2(c^2)(a^2)

= a^4+b^4+c^4+2a^2*2b^2+2b^2+2c^2+2c^2+2a^2

hope it helps!
