According to the Zero Power Rule of Integer Exponents, any non-zero number raised to the power of zero equals one. However, your expression involves multiplication by zero, not by a power of zero.
The expression you have is:
\[ 2.3 + (-1.478)(0) \]
Since anything multiplied by zero equals zero, we have:
\[ (-1.478)(0) = 0 \]
Now, substituting this back into the expression:
\[ 2.3 + 0 = 2.3 \]
Thus, the final answer is:
\[ 2.3 \]
