# Problem of expansion

N.B. i can't type the symbol for vector, so instead i will just type vect.

So, how can you solve:

|R - (vect.R' - vect.a)/|vect.R - vect.a| |

the term (vect.R' - vect.a)/|vect.R - vect.a| is less than one due to physics.

What's there to "solve"?

You havent stated what they are equal to.

It is asked to expand the expression

I need help expanding the expression I posted.
