To find the difference of \( 6.761 \times 10^{12} \) and \( 4.1 \times 10^{12} \), we can first express both numbers in the same format:
- \( 6.761 \times 10^{12} \)
- \( 4.1 \times 10^{12} = 4.1 \times 10^{12} \)
Now, since both numbers are expressed in terms of \( 10^{12} \), we can subtract the coefficients:
\[ 6.761 - 4.1 = 2.661 \]
Now we write the result back in scientific notation:
\[ 2.661 \times 10^{12} \]
So, the difference of \( 6.761 \times 10^{12} \) and \( 4.1 \times 10^{12} \) is:
\[ \boxed{2.661 \times 10^{12}} \]
