What is the completely factored form of d^4-81?

am i correct?

The answer to your question is: The second option is the correct one.

Step-by-step explanation:

You are wrong

                                 d⁴ - 81

                                (d²)² - (3²)²

                               (d² - 3²)(d² + 3²)

                               (d - 3)(d + 3)(d² + 9)

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
