Answer 1

Question

(a²-b²)² evaluate each of the following using appropriate identities

Answer-----

we can follow the property (a - b)^2 = a^2 + b^2 - 2ab

then, according to the property

a = a^2

b = b^2

now,

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

= a^4 + b^4 - 2 a^2 b^2

= a^4 + b^4 - 2 ab^2

Answer 2

Answer:

a⁴+b⁴-2a²b²

Step-by-step explanation:

(a²+b²) ²

(a²) ²+(b²) ²-2 (a²b²)

a⁴+b⁴-2a²b²
