l = 1500000
e = 12.5
r = 2
x = (l*l) * (e/r)
Result of x would be 14062500000000
so my question is now how to get "l" if i change "x"
i tried alot of things already but couldnt find a way to do it but there must be one
please let me know if anyone knows a way to get "l" if i change "x"
Thank you very much
