    Diophantine equations

    Hello, please help with sugesstions or solutions.

    1. Are there integers x and y so valid: x^2 -5xy +y^2 =3 ?

    2. Are there prime p and natural n so: 3p+1=k^3 ?

    3. Determine the naural numbers: 2<a<b<c<d<e so: \frac{1}{a}+\frac{1}{b}+\frac{1}{c}+ \frac{1}{d}+ \frac{1}{e} = 1 .

    Thank you for any help
