  3. a8 - b8 = ((a4)2 - (b4)2) [the difference of two squares] = (a4 + b4)(a4 - b4) = (a4 + b4)(a2 + b2)(a2 - b2) = (a4 + b4)(a2 + b2)(a + b)(a -b)

    a8 – b8 = ((a4)2 – (b4)2) [the difference of two squares]

    = (a4 + b4)(a4 – b4)

    = (a4 + b4)(a2 + b2)(a2 – b2)

    = (a4 + b4)(a2 + b2)(a + b)(a -b)
