Answer 3

To solve the expression (-4)·(-4.5)·2·(-2.5), you need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right). In this case, there are no parentheses or exponents, so we can proceed with the multiplication.

The expression can be rewritten as:

(-4) · (-4.5) · 2 · (-2.5)

Multiplying the negative numbers gives us a positive result:

(4) · (4.5) · 2 · (2.5)

Next, we can multiply the numbers together:

4 × 4.5 × 2 × 2.5

Calculating the multiplication:

4 × 4.5 = 18

18 × 2 = 36

36 × 2.5 = 90

Therefore, the result of (-4)·(-4.5)·2·(-2.5) is 90.
