square root of (E / M )= c

1. first you square the whole equation to get rid of the square root..

   so it becomes e/m= c squared

 2. then it is easy. you times the whole equation by m..

   so you get e= (c squared ) * m

if there is any step you don't understand.. let me know.. ill explain it in detail :)

Hope that helps..!!

Instead of making it letters/algebra, make it numbers. I didn't get it either until I did this and now I can do it easy. Try it
