The expression \( N = 1.23 \times 10^0 \) means that \( N \) is equal to \( 1.23 \) multiplied by \( 10 \) raised to the power of \( 0 \).
Since any non-zero number raised to the power of \( 0 \) equals \( 1 \), we have:
\[ 10^0 = 1 \]
Therefore:
\[ N = 1.23 \times 1 = 1.23 \]
So, \( N \) equals \( 1.23 \).
