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
First error is that the legs are a and b so a should be x and b is 6 and c is 10 the second error is at the end they did not take the square root to get x by itself the real answer should be X^2 +6^2=10^2 X^2+36=100 X^2 =64 X=8
