4.1 × 105 - 3.4 × 10° = 4.1 × 105 - 3.4 = 409,000 - 3.4 = 408,996.6
In scientific notation, this is approximately 4.09 × 10⁵.

It’s wrong
I apologize for the incorrect answer.
The correct evaluation is as follows:
4.1 × 10^5 - 3.4 × 10^0
First, let's simplify each term separately:
4.1 × 10^5 = 410,000
3.4 × 10^0 = 3.4
Now, subtract the second term from the first term:
410,000 - 3.4 = 409,996.6
To express this answer in scientific notation, we need to move the decimal point to the right until there is only one non-zero digit to the left. In this case, we need to move the decimal point 5 places to the left:
409,996.6 = 4.099966 × 10^5
Therefore, the answer in scientific notation is 4.099966 × 10^5.
