Answer 2

To evaluate the expression 0.4*(-10)³ - 7*(-10)² + 64, you should follow the order of operations, which is typically remembered using the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Here's how you can calculate it step by step:

1. Start with the exponentiation:

   • (-10)³ = -10 * -10 * -10 = -1000
   • (-10)² = -10 * -10 = 100

2. Now, apply multiplication and subtraction:

   • 0.4 * (-1000) = -400
   • 7 * 100 = 700

3. Finally, add and subtract:

   • (-400) - 700 + 64 = -1100 + 64 = -1036

So, the result of the expression is -1036.
