Find all 3 digit numbers such that by adding the first digit, the square of the second and the cube of the third you get the original number, for example 1 + 3^2 + 5^3 = 135.

Find all the triples of numbers a, b, c such that each one of them plus the product of the other two is always 2.

This is a beautiful result involving a parabola and parallels.

Use the following identities:

to find the highest power of $2$ and the highest power of $3$ which divide $5^{36}-1$.
