To solve \( 6.25 \cdot 10^{6} - 4.73 \cdot 10^{6} \), we can factor out \( 10^{6} \) from both terms:
\[ (6.25 - 4.73) \cdot 10^{6} \]
Now we calculate \( 6.25 - 4.73 \):
\[ 6.25 - 4.73 = 1.52 \]
Now we can multiply this result by \( 10^{6} \):
\[ 1.52 \cdot 10^{6} \]
Thus, the final answer is:
\[ 1.52 \cdot 10^{6} \]
