The greatest common factor for 21 is 7
For 30 is 15
49 is 7
I’m no totally sure but i think that is right
Answer:

Step-by-step explanation:
We want to simplify:

We rewrite as positive index to get:

This simplifies to

This will finally give us:

We cannot simplify further.
Hence the simplest form is
