0 , 16 b 4 + c 2 − 0 , 8 b 2 c

To simplify the expression, we will first perform the operations indicated.

Starting with \(16b^4 + c^2 - 0.8b^2c\), we can drop the zero term as it does not affect the sum. So, we have: \(16b^4 + c^2 - 0.8b^2c\)

Therefore, the simplified expression is: \[16b^4 + c^2 - 0.8b^2c\]
