Let us use the first 3 digits of PI, i.e. 3,1,4 to create numbers from 1 to 50, using only basic math. operators.
Not all the digits must be used, but none can be repeated.

Examples (out of this range): 52= 13*4; 65=4^3+1; 84=14*3!

Only few numbers cannot be achieved.

Please show your list.

So far 4 numbers were not resolved: 39,45,46,50.

For 2 of them I have a valid solution within the set of (concatenation, +, -,  *, -, ^, !, sqrt ), in both solutions  one of the bolded symbols is used twice.

In my list 2 numbers are still not covered.

So - we still have a challenge.
