M is greater than 4 as

M = 4^1/2 + 4^3/4 + 4^1/4

now 4^1/2 is 2
4^1/4 is 2^1/2 or 1.414
and 4^3/4 will be greater than 4^1/2 that is 2 so
M > 4+1.414
M> 5.414
It ain't how hard you hit; it's about how hard you can get hit, and keep moving forward. How much you can take, and keep moving forward. That's how winning is done
