0 , 16 b^4 + c ^2 − 0 , 8 b ^2 c

It appears that you have provided a list of expressions involving variables b and c. Let's simplify each expression:

1. 0 = 0 (since any number multiplied by zero is zero)
2. 16b^4 + c^2 = 16b^4 + c^2 (this expression cannot be simplified further)
3. 0 = 0 (since any number multiplied by zero is zero)
4. 8b^2c = 8b^2c (this expression cannot be simplified further)

If you have any specific questions or need further assistance with these expressions, feel free to ask!
