Answer 2

Answer:

a(a−b)(a+b)(a  ^2+ab+b  ^2 )(a  ^2  −ab+b ^ 2  )

Step-by-step explanation:

a  ^7  −ab  ^6

=a(a  ^ 6   −b  ^ 6 )

= a((a  ^3 )  ^2 −(b  ^3  )  ^2  )

= a(a  ^ 3  −b  ^3  )(a  ^3  +b  ^ 3  )

=a(a−b)(a  ^2  +ab+b  ^2  )(a+b)(a  ^2  −ab+b  ^2  )

Ans: a(a−b)(a+b)(a  ^2+ab+b  ^2 )(a  ^2  −ab+b ^ 2  )
