The Zero Power Rule of Integer Exponents states that any non-zero number raised to the power of zero equals one. In this case, we have \((-1.478)^0\).
So, we can simplify the expression:
\[ (-1.478)^0 = 1 \]
Now, substituting this back into the original expression:
\[ 2.3 + (-1.478)^0 = 2.3 + 1 \]
Now, we simply add:
\[ 2.3 + 1 = 3.3 \]
Therefore,
\[ 2.3 + (-1.478)^0 = 3.3 \]
