7a
No.
3a2+16a+5 = (3a+1)(a+5) when factored
Assuming A and B are equal to a and b, the GCF is 18ab. If not, it's just 18.
The GCF is 7.
1008a2b
The LCM of 5a and 16a is 80a
The LCM is 112a^3b.
240a3c2
The GCF is 18ab.
80a^3
18ab
Divide by 6a: 6a(a + 3b)
6a^b-18ab^2+24ab
17a + 21a + 45 = 38a+ 45
is there an error if the upstream circuit breaker is 16A TP and the downstream circuit breaker is 16A TPN?
The difference between 16A TP and 16A TPN isolator is the type of the circuit breaker that is used. The terminal design is the other difference.
