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.
The LCM of 5a and 16a is 80a
The LCM is 112a^3b.
The GCF is 18ab.
17a + 21a + 45 = 38a+ 45
Divide by 6a: 6a(a + 3b)
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.
