Answer:
=====================================
Step-by-step explanation:
Let's say we replace every copy of
with x
Doing so means we have the expression 5x-3x. That simplifies to 2x.
The last thing to do is replace the x with
and that's how we end up with
as the final answer.
----------
In short: we subtract the numbers out front, and then tack on a root 2 at the end.
As another example,
This is basically the same as saying 19x-11x = (19-11)x = 8x where
