Is this correct?

To subtract 3.2 x 10^4 from 1,845.19, we must first express 1,845.19 in scientific notation to align with the given expression.
1,845.19 can be written as 1.84519 x 10^3 (since we move the decimal point three places to the left).

Now we can subtract the two expressions:

1.84519 x 10^3 - 3.2 x 10^4

To subtract, we need to ensure the exponents are the same:

1.84519 x 10^3 = 0.0184519 x 10^5

Now we can subtract:

0.0184519 x 10^5 - 3.2 x 10^4

Since both expressions have the same exponent (10^5), we can subtract the coefficients:

0.0184519 - 3.2 = -3.1815481

Therefore, 1,845.19 - 3.2 x 10^4 equals -3.1815481 x 10^5.

No, the calculation is incorrect.

To subtract 3.2 x 10^4 from 1,845.19, you do not need to express 1,845.19 in scientific notation.

Simply subtract the numbers:

1,845.19 - 3.2 x 10^4 = 1,845.19 - 32,000 = -30,154.81
