This is tough to represent here without a full set of mathematical symbols.

Anyway, from Euler's Identity,

Code:
iπ e + 1 = 0
Therefore,

Code:
iπ e = -1
Thus,

Code:
iπ e + 4 = 3

Put this all together and you have:

Code:
√4 = 2 3 (3) = 27 2 • 27 = 54
Q.E.D.

In deference to Magic Mountain, as an aficionado of mathematics, a BSEE, an MSEE in Information Theory and a minor in mathematics, I just don't arbitrarily toss numbers into the trash bin. This is exact and precise math!
You are just using functions like I did. My solution was very precise, you just don't like it. you used the function f(x) = e^x, I used the function f(x) = [x] =n when n<=x<n+1. Heck even multiplication is a function and so is taking roots. However, I do like your solution.
