First, sorry about my english level because i am spanish.
I have a small question.
In Mathematica 5 I have the expression:
K = (112*e^2*Q)/(6561*a)
And I have definied the variable :
I = e^2/(2*a)
Then, i want to put K in the form:
K = (56/6561)*I*Q
Only i have replaced e^2/(2*a) by I in K expression.
HOW can I do it using Mathematica 5???
Thanks a lot.
