Eh Wah?

This is for smart people only:

M(2.71828)R^2(1/Y)^-1
X(force/acceleration)

I saw this yesterday. It almost reminded me of a post I made a few days ago.

For those who slept through high school, I will give you a few hints:

1. The Base of Natural Logarithms is e. e = 2.71828
2. X x X = X^2; R x R = R^2
3. X^-1 = 1/X; (1/X)^-1 = X; Try that with Y.
4. F=MA; Force = Mass x Acceleration.

Have you figured it out?
