To subtract 3.2 x 10^4 from 1,845.19, we can follow these steps:
Step 1: Write both numbers in scientific notation format.
1,845.19 becomes 1.84519 x 10^3 (move the decimal point 3 places to the left to get a number between 1 and 10)
3.2 x 10^4 remains the same.
Step 2: Subtract the numbers in scientific notation.
1.84519 x 10^3 - 3.2 x 10^4 = 1.84519 x 10^3 - 32 x 10^3
Since the exponent is the same, we can subtract the coefficients.
1.84519 - 32 = -30.15481
Step 3: Write the result in scientific notation format.
-30.15481 can be written as -3.015481 x 10^1 (move the decimal point 1 place to the right)
Therefore, the answer in scientific notation is -3.015481 x 10^1.
