Answer 2

To calculate the expression:

3.9 * 4.5 + 1.8 * 3.9 - 5.1 * 39

You can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right):

3.9 * 4.5 + 1.8 * 3.9 - 5.1 * 39

First, perform the multiplications:

17.55 + 7.02 - 198.9

Now, perform the additions and subtractions from left to right:

(17.55 + 7.02) - 198.9 24.57 - 198.9

Now, subtract 198.9 from 24.57:

-174.33

So, the result of the expression is -174.33.
