To evaluate the expression \( 13 - (14)^0 \), we first need to calculate \( (14)^0 \).
Any non-zero number raised to the power of 0 is equal to 1. Therefore,
\[ (14)^0 = 1 \]
Now substituting that back into the expression:
\[ 13 - (14)^0 = 13 - 1 = 12 \]
Hence, the value of \( 13 - (14)^0 \) is \( 12 \).
So the correct response is:
12
