a%5E8+%2Bb%5E8 = %28a%5E8+%2B+2a%5E4b%5E4+%2B+b%5E8%29+-+2a%5E4b%5E4 = %28a%5E4%2Bb%5E4%29%5E2+-+2a%5E4b%5E4 = %28a%5E4%2Bb%5E4%29%5E2+-%28sqrt%282%29a%5E2b%5E2%29%5E2%29 = %28a%5E4%2Bb%5E4%2Bsqrt%282%29a%5E2b%5E2%29%2A%28a%5E4%2Bb%5E4-sqrt%282%29a%5E2b%5E2%29


Next time do not forget to put a question in your post.

In this case I was smart enough to guess your question.

(it is because there is only one question in math associated with a%5E8+%2B+b%5E8: factor it).

But next time your post without a question can be disregarded and ignored (and remained unanswered).
