Irrational numbers. infinite zecimals right?
I always get the feeling that multiplying an irrational number with another number (any number) , you get infinite. what do you think?

I think you don't know how to multiply real numbers.

π * π^(-1) = 1
Zero decimals (necessary at least)

Square root of 2 is irrational. Square root of 2 times square root of 2 is 2, which I would not consider infinite.

forgot to mention it needs to be a natural number

Are there any non trivial solutions to this?

Let x be irrational. Let n be a natural number. If xn is rational then xn = a/b whet a and b are natural. But then x = an/b. a*n must also be natural, meaning x is rational. Contradiction, therefore xn must be irrational.
Elementary school math.

They're just numbers we can't write in base 10 you idiot

Define the multiplication operation on the reals. You can easily prove the reals are closed under this operation, so the product of two real numbers is not infinite.

Irrational numbers don't exist.
