To subtract the two numbers \( (2 \times 10^5) - (8.3 \times 10^3) \), we first need to express both numbers in terms of the same power of ten.
The first number is \( 2 \times 10^5 \).
The second number, written in the same power of ten, is:
\[
8.3 \times 10^3 = 0.083 \times 10^5
\]
Now, we can perform the subtraction:
\[
(2 \times 10^5) - (0.083 \times 10^5) = (2 - 0.083) \times 10^5 = 1.917 \times 10^5
\]
Thus, the answer in scientific notation is:
\[
\boxed{1.917 \times 10^5}
\]
The first number is \( 2 \times 10^5 \).
The second number, written in the same power of ten, is:
\[
8.3 \times 10^3 = 0.083 \times 10^5
\]
Now, we can perform the subtraction:
\[
(2 \times 10^5) - (0.083 \times 10^5) = (2 - 0.083) \times 10^5 = 1.917 \times 10^5
\]
Thus, the answer in scientific notation is:
\[
\boxed{1.917 \times 10^5}
\]
