Question

(а^2-b^2)^2 (a^2- b^2)^2​

Answer 1

Answer:

$\sf{(a^2 - b^2)}^2$ × $\sf{(a^2 - b^2)}^2$

$\sf{(a^4+b^4-2a^2b^2)}$ × $\sf{(a^4+b^4-2a^2b^2)}$

$\sf{a^4(a^4+b^4-2a^2b^2)}+b^4{(a^4+b^4-2a^2b^2)} -2a^2b^2{(a^4+b^4-2a^2b^2)}$

$\sf{(a^8+a^4b^4-2a^6b^2)} + \sf{(a^4b^4 +b^8-2a^2b^6)} - \sf{(2a^6b^2+2a^2b^6-4a^4b^4)}$

$\sf{(a^8+a^4b^4-2a^6b^2)} + \sf{(a^4b^4 +b^8-2a^2b^6)} + \sf{(-2a^6b^2-2a^2b^6+4a^4b^4)}$

$\sf{a^8+b^8-4a^2b^6-4a^6b^2+6a^4b^4}$
