I don’t understand math :/

Answer:
It's easy! Just simplify!
Step-by-step explanation:
So, I did one of these like this, and it's very easy!
To start you off, I'll share a way to do this.
First, separate all the common factors between the two terms:
[tex]\frac{9*2*c*c*c*c*c*c*c*c*d*d*d*d*d*d*d*d*d}{9*c*c*c*d*d*d*d*d*d}[/tex]
(took me a looooooonngggggg time to write that)
Next, cross out the common factors and multiply them back together again.
[tex]2c^{5} d^{3}[/tex]
Not the best strat. but a beginners one.
So there you have it!
Hope this helps!
P.S. Stay Safe!
