To evaluate the expression \( N = 6.54 \times 10^{-1} \):
- The term \( 10^{-1} \) means you are dividing by \( 10^1 \), which is \( 10 \).
- Thus, \( 10^{-1} = \frac{1}{10} = 0.1 \).
- Now, multiply \( 6.54 \) by \( 0.1 \):
\[ N = 6.54 \times 0.1 = 0.654 \]
Therefore, the value of \( N \) is \( 0.654 \).
