Okay so you subtract if there is division and u add when there is multiplying
Ex
m14n13/ (m3)3n5
You would first add the 3s as it is multiplying which will give u m14n13/m6n5 and now you will subtract them. M will subratact with M and n will subtarct with n
14-6 and 13-5 which will give u m8n8

Now u have m8n8 divide by m2n4 so u subtract them whicch will give u m6n4

Now u leave that and solve your second division. M subtract m and n subtract n which will give m2n4.

Now you have m6n4 x m2n4. You will add them as it is multiplying. Your answer will be m8n8. M8n8 is your final answer

Didn’t mention before but u add and subtract the exponents
